Task #714: rooms management submenu + rooms dashboard

- protocol.tsx: added collapsible "إدارة القاعات" nav group (giftsGroup pattern)
  containing لوحة القاعات (roomsDashboard, new), القاعات (rooms),
  حجز القاعات (bookings), إعدادات الحجوزات (bookingSettings, canManageRooms only).
- Deep-link slugs: /protocol/rooms-dashboard, /protocol/booking-settings.
- SlotsAdminSection moved from rooms tab to booking-settings tab; non-manager
  deep-link shows no-access empty state.
- New RoomsDashboardView (recharts): KPI cards, next-booking countdown,
  14/30-day area chart, by-room bar chart, by-status pie.
- API: new GET /api/protocol/rooms-stats (requireProtocolAccess), Riyadh-tz
  day boundaries, 30-day zero-filled daily series, byRoom/byStatus, nextBooking.
- i18n keys ar/en (tabs + protocol.roomsDash.* with Arabic plurals).
- Tests: artifacts/api-server/tests/protocol-rooms-stats.test.mjs (2 pass).
- Architect review passed; typechecks clean (pre-existing errors in
  executive-meetings.ts/push.ts untouched).
