The header status bar read the global /api/sync/status (videos_total +
channels_backfilling), so every user saw the whole catalog's numbers —
confusing and a small cross-user info leak (e.g. "3 syncing" for a user with 2
channels). It now uses /api/sync/my-status: the user's own available video count
and how many of their own channels are still being fetched
(channels_recent_pending). The pause control stays admin-only via an isAdmin prop.
- Header shows a live sync status (total videos + channels still backfilling, or
"paused"), polled every 30s
- Admins can pause/resume the background sync; a paused flag in app_state makes
scheduled jobs skip (migration 0006)
- GET /api/feed/count returns the number of videos matching the current filters;
shared filter builder keeps it in sync with /api/feed; shown above the feed
- /api/sync/status reports backfill progress, pending enrichment and paused state
