- delete server/services/jellyfin.ts, webhook.ts, mqtt.ts and their tests
- strip jellyfin/mqtt imports and startup calls from index.tsx and settings.ts
- remove /jellyfin, /mqtt, /mqtt/status, /mqtt/test, /jellyfin/webhook-plugin endpoints from settings router
- clean ENV_MAP and isEnvConfigured of jellyfin/mqtt keys
- add db/index.ts migrations for series_key, duration_seconds, scan_status, scan_error, last_scanned_at (new columns absent on older dev DBs)
- move idx_media_items_series_key out of SCHEMA into migrate() so it runs after the column is added
- fix all test fixtures: drop jellyfin_id/series_jellyfin_id column refs, update MediaItem/MediaStream object literals to match current types

root cause: all five job-insert sites in review.ts blindly inserted a
'pending' row, so a double-click on approve (or an overlap between
/approve-all and individual /approve) wrote N jobs for the same item.
job 1 stripped subtitles + reordered audio; jobs 2..N then ran the
same stale stream-index command against the already-processed file
and ffmpeg bailed with 'Stream map matches no streams'.
fix: funnel every insert through enqueueAudioJob(), which only writes
when no pending job already exists for that item. covers approve,
retry, approve-all, season approve-all, series approve-all.
