feat: housekeeping automation — auto-task on checkout + room status on done

Backend:
- Migration 023: housekeeping_settings table (checkout_auto, checkout_priority, inspection_after_clean)
- New route: GET/PATCH /api/hotels/:slug/housekeeping-settings
- bookings.ts: on checked_out → auto-create turnover task + mark room dirty + broadcast WS
- housekeeping.ts: on task done → update room status (inspect|clean per setting) + broadcast WS
- ws.ts: export broadcast() for use in other routes

Frontend:
- HousekeepingPage: load/save settings to API, live Loader on save button
- useHotelSocket: add housekeeping WS message types
- HousekeepingPage: subscribe to WS — new tasks appear instantly without refresh
- BookingModal: show total section when room + nights selected (not just when total > 0)
