d228676a56 fix(security): cross-event authz, SSE ticket flow, account hardening, audit logs
Follow-up to the comprehensive code review. Five batches:

1. Cross-event authorization: host_delete_upload, unban_user, and
   host_delete_comment now scope by auth.event_id. Adds
   Upload::find_by_id_and_event / soft_delete_in_event and a
   Comment::soft_delete_in_event variant that joins through upload.

2. Token exposure: SSE auth no longer puts the JWT in the URL.
   New /api/v1/stream/ticket endpoint mints a short-lived single-use
   ticket bound to the session; the EventSource passes ?ticket=...
   instead. Refuse to start in APP_ENV=production with the dev JWT
   sentinel; warn loudly otherwise.

3. Account hardening: per-IP+name rate limit on /recover (mitigates
   targeted lockout DoS), per-IP rate limit on /admin/login, random
   32-char admin recovery PIN (replaces "0000"), structured tracing
   events for wrong PIN, lockout, failed admin login, ban/unban/role
   change/pin-reset/host-delete.

4. DoS / correctness: comment listing paginated (LIMIT 50 + ?before=
   cursor), hashtag extraction whitelisted to ASCII alnum+underscore
   (≤40 chars) with unit tests, display_name / caption / comment body
   length validated in chars rather than bytes.

5. Cleanup: session-touch failures now logged, DATABASE_MAX_CONNECTIONS
   env var (default 10).

05f76514a2 fix(backend): JWT jti, NUL-byte guard, dev-only truncate endpoint
Two bugs surfaced while running the new E2E suite, plus a small test hook:

- jwt.rs: add a per-token `jti: Uuid` claim. Without it, two `create_token`
  calls in the same wall-clock second for the same (sub, role, event_id)
  produced identical JWT bytes — and identical sha256(token) hashes —
  which then collided on `session.token_hash UNIQUE` with a 500. Manifests
  in real use when an admin clicks "Anmelden" twice fast.

- auth/handlers.rs: reject display names containing 0x00. Postgres rejects
  NUL in TEXT columns with `invalid byte sequence for encoding "UTF8"` and
  the request leaks back as a 500. Now returns 400 with a clean message.

- handlers/test_admin.rs + main.rs: new POST /api/v1/admin/__truncate route,
  compiled in always but only **registered** when EVENTSNAP_TEST_MODE=1 is
  set on startup. Truncates every event-scoped table, reseeds config from
  migration defaults, wipes media on disk, and clears the in-memory rate
  limiter. RequireAdmin-gated so it's not anonymous even in test mode. In
  production builds (no env var) the route returns 404 — verified by the
  startup log message.

- services/rate_limiter.rs: add `clear()` so the truncate handler can wipe
  the in-memory window map between tests.

- Dockerfile: bump rust:1.87 → rust:1.88 (current dep tree needs it) and
  COPY ./migrations into the build context so the `sqlx::migrate!()` macro
  can resolve at compile time.

2761ac7db6 chore: rebuild export-viewer with the shared Tailwind theme
Pre-built output regenerated after frontend/export-viewer/src/app.css
started importing ../../src/tailwind-theme.css. Output now picks up the
same @theme tokens and class-driven dark variant as the live app, so
future viewer-side use of bg-primary / dark: utilities will resolve
identically to the main bundle.

2e98f5ddf5 backend(features): quota enforcement, PIN reset, /me, original download, toggles
- handlers/me.rs (new): GET /api/v1/me/context (profile + role + privacy_note
  + quota toggle state, fetched once on app bootstrap) and GET /api/v1/me/quota
  (live used / limit / active uploaders / free disk).
- handlers/upload.rs:
  - quota enforcement via the dynamic formula
    floor((free_disk * tolerance) / max(active_uploaders, 1)),
    gated by quota_enabled + storage_quota_enabled toggles
  - new GET /api/v1/upload/{id}/original — unauthed by design
    (matches /media/previews/* — URL is the secret) so it works as
    <img src> / <video src> / window.open
  - rate-limit toggle wiring (rate_limits_enabled + upload_rate_enabled)
- handlers/host.rs:
  - POST /api/v1/host/users/{id}/pin-reset — Host may reset guest PINs,
    Admin may reset guest + host PINs (never another admin or self).
    Returns the freshly-generated plaintext PIN once; emits a global
    pin-reset SSE so the affected user's device can clear its localStorage.
  - set_role guard expanded so hosts can demote other hosts (not self,
    never admins) — backend match for the doc'd permission model.
- handlers/admin.rs: ALLOWED_KEYS split into NUMERIC_KEYS / BOOL_KEYS /
  TEXT_KEYS with per-kind validation; saving privacy_note broadcasts an
  event-updated SSE so other clients refresh live.
- handlers/feed.rs, handlers/admin.rs (export), auth/handlers.rs:
  rate-limit toggle wiring at every limiter call site.
- auth/handlers.rs: when an expired PIN lockout is detected on /recover,
  reset failed_pin_attempts to zero before the bcrypt check — without
  this every wrong PIN re-locked the user after the cooldown.
- main.rs: wire startup_recovery + spawn_periodic_tasks, register the
  new /me/context, /me/quota, /upload/{id}/original, and
  /host/users/{id}/pin-reset routes.

141c918dd5 backend(infra): shared config helper, startup recovery, periodic maintenance
Foundations for the v0.16 features. No new endpoints here — those land in
the next commit on top of these.

- migrations 008 + 009: commit the load-bearing compression_status column
  that was uncommitted on disk; add 009_feature_toggles seeding the master
  + per-endpoint rate-limit switches, the master + per-area quota switches,
  and the admin-editable privacy_note.
- services/config.rs (new): get_str / get_i64 / get_usize / get_f64 / get_bool
  consolidating the scattered helpers that lived in three handlers.
- services/maintenance.rs (new):
  - startup_recovery() — resets compression_status='processing' and
    export_job.status='running' rows orphaned by a previous crashed
    instance, so users never see permanent "Wird vorbereitet…" spinners.
  - spawn_periodic_tasks() — hourly cleanup of expired sessions (rows
    were never pruned) + rate-limiter HashMap pruning (windows kept one
    entry per IP forever).
- services/jobs.rs (new sketch): BackgroundJob trait + JobContext for
  future jobs to plug into the same progress + SSE pipeline as
  compression/export. Not wired yet — codifies the convention.
- services/compression.rs: 120s hard timeout + kill_on_drop on ffmpeg
  so a malformed video can't hang and leak a worker semaphore permit.
- services/rate_limiter.rs: new prune() called from the periodic task.
- state.rs: SseEvent::new() constructor so event-type strings stay
  consistent instead of being typed inline at every emit site.
- models/user.rs: UserRole::as_str() for /me/context serialization.
- models/upload.rs: soft_delete() now runs in a transaction and
  decrements the uploader's total_upload_bytes (GREATEST(0, …) guard) —
  fixes a quota drift where deleting reclaimed no quota.
- Cargo.toml + Cargo.lock: add `infer = "0.15"` (multipart MIME sniffing
  used by the upload handler).

9a0ceeced7 docs: realign blueprint with shipped state + add feature/journey/ideas docs
- PROJECT.md, README.md, TEST_GUIDE.md: status line refreshed; rate-limiter
  doc-vs-code drift fixed; HTML export section rewritten for the SvelteKit-
  static viewer; SSE event names + new events documented; config seed block
  extended with planned toggles + privacy_note; decision log entries added.
- docs/CONCEPT_HTML_VIEWER.md, docs/CONCEPT_MOBILE_UI.md: banner the design
  intent as shipped; point at the source-of-truth code paths.
- docs/CONCEPT_DIASHOW.md: planned-then-shipped design for the live diashow
  (two-queue policy, pluggable transitions, data-mode aware).
- docs/FEATURES.md: capability matrix by role (Guest / Host / Admin) plus
  prose per area (auth, posting, feed, moderation, admin, export, gestures,
  data mode, quotas, privacy note, extensibility).
- docs/USER_JOURNEYS.md: step-by-step flows for every supported scenario,
  including PIN reset by host, data mode, privacy note, gestures, and the
  admin toggles.
- docs/IDEAS.md: speculative extensions (global diashow, reactions,
  multi-tenancy, animation pack, etc.) — explicitly out of v0.16 scope.
- backend/migrations/README.md, frontend/src/lib/README.md: codify the
  "never edit a shipped migration" rule and the lib/ conventions
  (one store per concern, gestures via actions, sheets via ContextSheet,
  transitions as drop-in components).

ffc926bf4d feat: replace HTML export with SvelteKit viewer
Replace the minijinja-based HTML export with a full SvelteKit static
viewer app. The new export produces a ZIP with:
- Pre-built viewer assets (index.html + JS/CSS bundle)
- data.json with all posts, comments, tags, and like counts
- Processed media: 400px thumbnails for grid, full images (2000px
  cap if >5MB), video thumbnails via ffmpeg

Remove minijinja dependency, add include_dir to embed viewer assets
at compile time. Update Dockerfile to copy static/ for builds.

d0a199e9b5 fix: HTML export tojson filter + authenticated file download (v0.14.1)
- Enable minijinja 'json' feature so the tojson filter is available in
  the Memories.html template (was causing 'unknown filter' render error)
- Replace window.location.href downloads with fetch+blob so the
  Authorization header is sent (window.location.href caused 401)

0351e967c0 feat: unique display names + inline recover on join (v0.13.1)
Backend: migration 007 adds a case-insensitive unique index on user names
per event. join endpoint returns 409 conflict when the name is taken.
find_by_event_and_name uses LOWER() for case-insensitive recovery.

Frontend: join page handles 409 with a name-taken view — amber warning,
name-choice tips, inline PIN recovery form, and "Anderen Namen wählen"
button. Test guide updated with Steps 8 and 9.

de0e395a9e feat: auto-retry uploads when rate limited (v0.13.0)
Backend: rate limiter gains check_with_retry() returning seconds until
the next slot opens. Upload 429 responses include retry_after_secs in
JSON and a Retry-After header.

Frontend: upload queue catches 429 as RateLimitError, resets affected
item to pending, schedules processQueue() for the server-reported delay,
and shows a live countdown banner in the queue UI.

3dc69e6c6d fix: upload body limit, role case, and connection drain (v0.12.1)
- Disable Axum's 2 MB default body limit on the upload route so large
  photos/videos are accepted without HTTP 400
- Serialize UserRole as lowercase in JWT so the frontend role checks
  ('guest'/'host'/'admin') match correctly
- Drain multipart body before returning early upload errors (rate-limit,
  ban, event-lock) to keep the HTTP keep-alive connection clean and
  prevent cascading Netzwerkfehler / empty-500 responses
- Add TraceLayer for request logging and Vite dev proxy config

989d88022a feat: implement rate limiting across all API endpoints
Add sliding-window in-memory RateLimiter service (Arc<Mutex<HashMap>>)
with per-IP and per-user-id limits on all public endpoint classes:
- POST /api/v1/join: 5/min per IP
- GET /api/v1/feed: configurable per IP (feed_rate_per_min, default 60)
- POST /api/v1/upload: configurable per user (upload_rate_per_hour, default 10)
- GET /api/v1/export/zip|html: configurable per IP (export_rate_per_day, default 3)
Limits are hot-reloadable via the config table. All 429 responses use
German error messages. Client IP is read from X-Forwarded-For (Caddy).

258e2bd84d feat: implement export engine
Add async ZIP and HTML offline viewer export workers, download endpoints,
and a guest-facing /export page.

Backend — export workers (tokio::spawn, run after gallery release):
- ZIP worker: streams all non-deleted originals into Gallery.zip via
  async_zip (Stored compression), organised into Photos/ and Videos/
  with {date}_{uploader}_{id}.{ext} filenames; updates progress_pct in DB
- HTML worker: renders Memories.html via minijinja template (self-contained:
  inlined CSS + JS, relative media paths); packs it with README.txt and
  all media into Memories.zip (Deflate for text, Stored for media)
- Both workers mark export_job status (running → done/failed), update
  export_zip_ready / export_html_ready on the event, and broadcast SSE
  export-progress + export-available when both complete

Backend — new endpoints (AuthUser):
- GET /export/zip   → streams Gallery.zip if export_zip_ready
- GET /export/html  → streams Memories.zip if export_html_ready
- GET /export/status → released flag + per-type status/progress (moved from admin)

Memories.html features: warm keepsake aesthetic, responsive grid, fullscreen
lightbox with captions/comments/likes, client-side hashtag filter chips,
XSS-safe JS, fully offline (no external deps)

Frontend — /export page:
- Locked state: padlock illustration + message
- Released state: ZIP and HTML cards with progress bars (SSE-driven),
  download buttons enabled only when ready
- HTML guide modal (unzip instructions + Wi-Fi tip) before download begins

monitoring, and export job status, plus a public export/status endpoint.

Backend — new /api/v1/admin/* endpoints (RequireAdmin auth):
- GET  /admin/stats           → user/upload/comment counts + disk usage
- GET  /admin/config          → all config key/value pairs
- PATCH /admin/config         → update any subset of config keys; validates
                                 key whitelist and numeric values
- GET  /admin/export/jobs     → export_job rows for the event

Backend — public (AuthUser) endpoint:
- GET  /export/status         → released flag + zip/html job status/progress

Frontend — /admin page:
- Stats grid: guest count, upload count, comment count
- Disk usage bar with GB/MB formatting; red ≥ 90%, amber ≥ 75%
- Config form: labelled numeric inputs for all eight config keys,
  sends only changed values on save
- Export jobs list: type label, status badge, progress bar for running jobs,
  error message if failed; manual refresh button

71a2987a3e feat: implement host dashboard
Add Host Dashboard for event and guest management, accessible at /host.

Backend — new /api/v1/host/* endpoints (RequireHost auth):
- GET  /host/event                    → event name + lock/release state
- POST /host/event/close|open         → lock or unlock uploads; SSE broadcast
- POST /host/gallery/release          → set release timestamp, enqueue export jobs
- GET  /host/users                    → all guests with upload count & bytes
- POST /host/users/{id}/ban           → ban with optional upload-hide choice
- POST /host/users/{id}/unban         → lift ban
- PATCH /host/users/{id}/role         → promote guest→host or demote host→guest
- DELETE /host/upload/{id}            → host-level soft-delete + SSE
- DELETE /host/comment/{id}           → host-level soft-delete

Frontend — /host page:
- Event controls: lock/unlock toggle and release-gallery button with status badges
- Guest table: display name, role badge, upload count, storage used
- Ban flow: modal asking whether to keep or hide the user's uploads
- Promote/demote buttons respecting caller role (host can promote guests; admin can demote hosts)
- auth.ts: getRole() decodes JWT payload client-side to gate the route
