Deploy Vault CMS / deploy (push) Failing after 38s
Fix watch tracking, video unlocking and access-control gaps
Watch progress and unlocking:
- Player samples the playhead and reports the ranges actually played,
  so skipped sections earn no credit and early plays are not lost
- Server merges ranges into compact segment rows; progress never regresses
- Single 80% unlock rule enforced server-side (lib/watch-progress.ts);
  the Unlock button and automatic unlock now agree
- Lock state and progress bar update live from each progress save
- Playlist is derived from the video, so unlocks work for shared
  playlists and for links from watch history and liked videos
- First/previous video decided by playlist position, not index numbers

Access control:
- Video API and HLS/MP4 routes require a signed-in viewer who is
  enrolled and has the video unlocked; thumbnails require sign-in
- Enrolment sync reads course codes from the allow-list, not the request
- /api/admin/meta is admin-only
- Account status, role and levels are re-checked from the database
  during a session, so deactivated students lose access within a minute
