Implements the facility-classes-booking-dashboard plan (backend): - Facility.BookingMode (single Scheduled/AdHoc choice) replaced with independent SupportsClasses/SupportsBooking flags, so one facility can run a class and accept walk-in bookings; a running class now blocks walk-in booking for its window on both create and reschedule. - CustomerPlan.GrantsGymAccess + CustomerPlanClass join table let a customer hold one gym-access plan plus any number of class-only plans. Replaced the old single-subscription resolution (GetActiveSubscriptionByCustomerId/HasAnyActiveSubscriptionAsync) with gym-access-aware and class-aware resolvers across booking creation/cancellation, plan assignment, and customer self-service. Fixed ChangeMembershipPlan/renewal plan-changes, which resolved "the subscription to replace" by most-recent-created and would have deactivated a member's class subscription instead of their gym one. - New FacilityClass model: recurring class definitions (Daily/Weekly/ Monthly/Custom) with lazy occurrence generation (8-week horizon, race-safe via a unique index) and proper unlimited-capacity handling. "Mark not held" replaces the old bare-cancel: cascades to cancel and refund every confirmed booking on the occurrence through the same core CancelBooking uses, and frees the slot for walk-in booking. Scheduling conflicts (a walk-in booking now overlapping a class) are surfaced for staff to resolve via the existing Reschedule flow. - Renamed the pre-existing "AdHoc" booking-mode terminology to "WalkIn" throughout (routes, methods, DTOs, the stored BookingMode value) for a clearer, simpler name.
