// API contract tests for GET /protocol/rooms-stats (لوحة بيانات القاعات).
// Covers:
//   1. Auth guard: unauthenticated request -> 401.
//   2. Shape: rooms{active,inactive}, todayBookings, weekBookings,
//      pendingBookings, nextBooking, daily (30 zero-filled Riyadh days),
//      byRoom, byStatus.
//   3. Counters reflect seeded data: a pending booking tomorrow shows up in
//      weekBookings + pendingBookings + nextBooking + byRoom/byStatus;
//      a cancelled booking is excluded from occupancy counters.
//
// Seeded rows are deleted in `after`; no global state is mutated.
