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).
