ScreenTinker afbe113acf Security audit remediation: auth, IDOR, XSS, hardening 
- Device WebSocket authentication: devices get a device_token on
  registration, must present it on reconnect. All WS events require
  prior auth. Timing-safe token comparison.
- IDOR fixes: ownership checks on schedules (device, week), layouts
  (all CRUD, zones, duplicate, device assign), video-walls (content,
  device-config).
- XSS prevention: shared esc() helper in utils.js, fixed 13 innerHTML
  injection points across 9 frontend files.
- OAuth hardening: no longer silently overwrites auth_provider on
  accounts with local passwords (returns 409).
- JWT pinned to HS256 for sign and verify.
- Password policy: change endpoint now requires 8 chars (was 6).
- HSTS header enabled (max-age 1 year, includeSubDomains).
- Stripe webhook rejects unsigned payloads when no secret configured.
- Screenshot size validation (max 2MB base64).
- Rate limiting on exports, imports, content operations.
- Content file serving checks playlist_items instead of old assignments.
- Content ownership verified in device-groups assign-content.

ScreenTinker f57fc5ad81 Security hardening: auth checks, XSS escaping, input validation 
- Add requireGroupOwnership middleware to all group endpoints
- Whitelist allowed command types (screen_on/off, launch, update, reboot, shutdown)
- Validate color format as #RRGGBB
- Escape all user-controlled strings (device/group names, emails) in dashboard HTML
- Restrict trust proxy to first hop only (prevents IP spoofing + rate limit bypass)

ScreenTinker e2879fff58 Instant playlist push, fix YouTube looping, auto-fetch video titles 
- 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)
