fabi 36fe59caa5 fix(user-flow): persona-audit fixes — ban replay, locked-upload data loss, host UX, admin session
Follows the perf + security + user-flow work with a role/persona audit (guest, host,
admin, projector) and fixes across three review rounds. Highlights:

HIGH
- Ban now replays on reconnect. A ban isn't a soft-delete, and the `user-hidden` SSE has
  no replay, so a client that missed it (esp. the unattended diashow) kept cycling a
  banned user's slides. New `uploads_hidden_at` (migration 013) + `hidden_user_ids` in
  /feed/delta; feed + diashow evict those users. Applied even on a truncated delta.

MEDIUM
- Locked-upload data loss: a photo staged offline during a lock/release was purged as a
  terminal 4xx and lost when the host reopened. New reversible `uploads_locked` error code;
  the queue keeps the blob and auto-resumes on the `event-opened` SSE.
- Reopen after release now warns (ConfirmSheet) that it revokes the published keepsake.
- Host "forgotten-PIN" badge updates live (`pin-reset-requested` was broadcast but never
  in KNOWN_EVENTS / subscribed); host page also refetches on `pin-reset` so a two-host
  race can't hand out a conflicting PIN.
- Ban modal copy fixed (read-only ban, not "session ended"); Degradieren/Sperren/Entsperren
  hidden on peer-host rows for non-admins (they always 403'd).
- Host dashboard shows live keepsake generation progress / ready state + link to /export.
- Admin JWT moved to sessionStorage (§11.1) to bound exposure on shared devices.

Export generation guard (H1 from the prior round, hardened): per-(event,type) `release_seq`
(migration 012) with seq-guarded claim/finalize/mark_failed/update_progress, per-generation
temp/final paths, download follows `file_path`, prune only strictly-older generations.

LOW: diashow coalesces upload-processed (avoids self-rate-limit); event-closed reconciles
galleryReleased; /recover gains a forgot-PIN request + drops a stale cached PIN on 401;
delta `>=` tie-break + 429 retry; misc copy/labels.

Adds e2e: ban-replay, upload-lock-code, and rewrites export-reopen-rerelease with a
data-completeness test. Reconciles USER_JOURNEYS §9/§11.

Verified: cargo build clean, 40 unit tests, svelte-check 0 errors, 33 frontend unit
tests, 155 e2e passing on chromium-desktop.

lib/ conventions

Short rules. The patterns we already follow as of v0.16 — write new code that fits.

One store per cross-cutting concern. A single *-store.ts file owns each one:

  • auth.ts — JWT / PIN in localStorage, isAuthenticated writable
  • ui-store.ts — bottom-nav visibility, upload-sheet open state, FAB badge count
  • data-mode-store.ts — Saver vs Original media-loading preference
  • privacy-note-store.ts — admin-configured Datenschutzhinweis text
  • quota-store.ts — live per-user storage snapshot
  • upload-queue.ts — IndexedDB-persisted upload queue + processing state

Don't import these into other stores unless strictly necessary; let pages compose them.

DTOs mirror Rust types. All TS interfaces live in types.ts. Each one carries a // mirrors backend/src/path::TypeName comment so the two stay searchable. If you add a Rust DTO, add the TS twin in the same PR.

Gestures via Svelte actions in actions/. Long-press, double-tap, future swipe — each is a use: action that fires a CustomEvent. Components stay free of gesture plumbing.

Reusable bottom sheets via ContextSheet.svelte. Pass an actions: ContextAction[] array. Any page that needs a long-press / kebab context menu uses the same primitive.

SSE relays are listed in sse.ts::KNOWN_EVENTS. New server event → add one entry to that array, that's it.

Diashow transitions live in diashow/transitions/. Each is a Svelte component plus one entry in transitions/index.ts. Adding a new animation is two-line work; no diashow code needs to change.

No new global stores beyond the list above unless the new concept is genuinely app-wide. Page state belongs in the page.
