Phase 4 group scheduling: schema migration adds group_id to schedules with
CHECK constraint, scheduler evaluates group+device schedules with priority,
group deletion converts schedules to per-device copies. Dashboard gets
playlist assignment dropdown and current playlist label on group headers.
Player persists audio unlock state in localStorage so version reloads
don't lose audio on unattended displays.

Schedule CRUD now includes playlist_id field. List queries join playlist name.
Scheduler tracks active overrides per device and reverts to original
playlist/layout when no schedule is active.

Replaces the assignments-table query with a playlist_items query keyed on
device.playlist_id. Also eliminates the duplicate payload builder in
scheduler.js — it now calls the shared buildPlaylistPayload.
