Add role permissions, loyalty accrual rules, guest statuses, and room service guest page

- UsersPage: add "Роли и права" tab with per-module permission editor per role; create/delete custom roles
- LoyaltyPage: add "Правила начисления" tab with togglable accrual rules editor; add "Ручное начисление" tab with guest search by name/phone/email, add/deduct points with reason and history; fix banner text (HotelSync is a PMS, not a hotel chain)
- GuestsPage: add "Статусы гостей" tab (moved from Settings)
- SettingsPage: remove Guests section; add compact calendar toggle in Appearance; toggle persists via localStorage
- BookingCalendar: read compact mode default from localStorage
- App.tsx: add public route /room-service/:slug → GuestRoomServicePage
- GuestRoomServicePage: new public guest-facing page for ordering room service with menu, cart, payment, and order status tracking
- RoomServicePage: QR/link sharing, payment mode toggles, new order notifications
- RentalPage/rentalData: buffer time between bookings (bufferMinutes field)
