package admin

// Package admin contains tests for admin booking management endpoints.
//
// Test Coverage:
//   - GetAllAdminBookingsHandler: GET /api/admin/bookings - List all bookings with filters
//   - SearchAdminBookingsHandler: POST /api/admin/bookings/search - Search bookings
//   - GetAdminBookingHandler: GET /api/admin/bookings/{id} - Get booking details
//   - AdminCreateBookingForUserHandler: POST /api/admin/bookings - Create booking for user
//   - ProgressBookingHandler: PUT /api/admin/bookings/{id}/progress - Update booking status
//   - ConfirmBookingHandler: POST /api/admin/bookings/{id}/confirm - Confirm booking
//   - AdminCancelBookingHandler: POST /api/admin/bookings/{id}/cancel - Cancel booking
//   - AdminListEditRequestsHandler: GET /api/admin/bookings/edit-requests - List edit requests
//   - AdminApproveEditRequestHandler: POST /api/admin/bookings/{id}/approve-edit - Approve edit
//   - AdminRejectEditRequestHandler: POST /api/admin/bookings/{id}/reject-edit - Reject edit
//
// Authentication: All endpoints require admin role (403 for non-admins).
