The SW was causing "unexpected error" on video/image fetches due to
range request handling, opaque response caching, and stale SW races.
Fix: SW now ONLY caches player page + socket.io JS for offline boot.
Content files are left to browser native HTTP cache (server already
sets Cache-Control: public, max-age=2592000, immutable).
Also: auto-reload player when new SW activates so deploys take effect
immediately without manual hard refresh.
Bumped cache to v5 — activate purges all old caches (including the
broken rd-content-v1 content cache).

Bug 1 (SW): Rewrote service worker fetch handler:
- Skip range requests (video seeking) to avoid caching partial responses
- Skip non-GET requests entirely
- Use ignoreSearch on cache match to avoid query-param misses
- Don't cache opaque cross-origin responses
- Outer catch on Cache API failures
- Don't intercept catch-all requests (let browser handle natively)
- Bump cache version to v4 to purge broken cached responses
Bug 2 (auth): Playlist refresh register was missing device_token,
causing auth rejection every 5 minutes. Fixed by including token
in the refresh-register emit. Added diagnostic logging on both
client and server for token validation failures.

Web player:
- Cache playlist JSON to localStorage on every update
- Restore and start playing immediately on boot before connecting
- Clear cache on unpair/reset
Android app:
- Cache playlist JSON to EncryptedSharedPreferences on every update
- Restore cached playlist on cold-start, play from disk-cached content
- Update cache on content deletion, clear on unpair
Server (device socket):
- Fingerprint reconnect: issue fresh token instead of rejecting
- Send device:paired on fingerprint recovery for claimed devices
- Add status logging and dashboard notification on fingerprint reconnect

Follows up on the security audit remediation (afbe113) which added
device_token auth to the WebSocket /device namespace.
Android player (ServerConfig.kt, WebSocketService.kt):
- Persist device_token in EncryptedSharedPreferences alongside device_id
- Send device_token in device:register on reconnect and playlist refresh
- Save/overwrite token from device:registered response (handles legacy
devices getting their first token)
- Handle device:auth-error by clearing credentials and showing pairing screen
- clearDeviceCredentials() method wipes device_id, device_token, is_paired
Web player (player/index.html):
- Save deviceToken in localStorage config from device:registered response
- Send device_token in register() payload on reconnect
- Handle device:auth-error and device:unpaired events — clear config and
show re-pair UI

- Push playlist updates to devices instantly via WebSocket on all
assignment mutations (add, update, delete, reorder, copy)
- Fix YouTube videos skipping early: remove duration_sec timeout (was
defaulting to 10s), use generation counter to ignore stale player
callbacks, disable YouTube loop param for multi-item playlists
- Auto-fetch YouTube video title via oEmbed API when no name provided
- Show actual video duration in M:SS format in playlist instead of
misleading assignment duration_sec
- Pre-fill server URL from origin on web player setup
- Bump playlist poll interval to 5min (fallback only, push is primary)

- Replace raw iframe YouTube embeds with official YT IFrame Player API for proper
error handling (150/153/100/101) and unmute support
- Fix playlist not updating when single item changes by comparing full content
fingerprint (id + url + filepath + filename) instead of just content_id
- Add click-to-unmute overlay for YouTube since iframe swallows click events
- Remove hardcoded origin param from server-side YouTube URLs (caused Error 153
when player domain differs from server)
- Switch service worker to network-first for player assets so deploys take effect
without hard refresh; keep cache-first for uploaded content

- Add mute=1, enablejsapi=1, and origin params to YouTube embed URLs
- Fix applies at creation time (content route) and playback time (player)
- Existing YouTube content gets fixed params via fixYoutubeUrl() helper
- Also fixes content library preview iframe

- Loop single-video playlists natively instead of destroying/recreating the element
- Skip caching HTTP 206 partial responses in service worker (video range requests)
- Bump service worker cache version to invalidate old cache
