Security fixes:
- Critical: Add ownership checks to assignments PUT/:id and DELETE/:id (IDOR)
- Critical: Add ownership checks to assignments copy-to endpoint for both devices
- High: Validate device ownership when adding to device groups
- High: UUID-validate content ID before LIKE query + scope to owner's playlists
- Low: Handle FK violations gracefully in playlist discard (deleted content/widgets)
- Low: Escape mime_type with esc() in playlist item display (XSS)
Bug fix:
- Device-detail mutation handlers now reload full page to show draft banner

Schema: add status and published_snapshot columns to playlists table.
Migration snapshots all existing playlists as published (idempotent via schema_migrations).
Devices always receive the published_snapshot, not live playlist_items.
Edits from device-detail/groups auto-publish immediately (display updates instantly).
Edits from playlist detail page go to draft (requires explicit publish).
POST /playlists/:id/publish snapshots and pushes to all devices.
POST /playlists/:id/discard reverts playlist_items from published snapshot.
Content deletion scrubs references from all published snapshots.
Frontend: draft badge in playlist list, prominent yellow banner with publish/discard
buttons on playlist detail and device detail pages.

Users need to see migrated playlists immediately. The toggle still
allows hiding them if desired.

with thumbnails, duration editing, drag-to-reorder, remove.
Add-item modal: content/widget picker with search and tabs.
All user strings escaped via esc() helper for safe innerHTML.
