feat: TTLock integration + fix agent offline status

- Add TTLock electronic lock module: settings page, room-lock mapping,
  card issuance via agent command (ttlock:write_card)
- Fix agent offline: EquipmentPage now polls every 30s + reacts to
  workstation:online/offline WebSocket events instantly
- Backend broadcasts workstation online/offline events to hotel clients
  via existing WebSocket (agent-ws.ts)
- New DB migration 048_ttlock.sql: hotel_ttlock_config, room_lock_mappings,
  card_issuances tables
- New backend routes: GET/PATCH ttlock/config, POST ttlock/token,
  GET ttlock/locks, POST/DELETE ttlock/room-locks, POST issue-card
- "Выдать ключ (TTLock)" button in BookingDetailPanel for confirmed/checked_in
- TTLock page added to sidebar under Настройки
