Refactor CustomerPlanService to use FacilityRepository, remove PlaceService, and introduce RfidTagService

- Updated CustomerPlanService to replace references to PlaceRepo with FacilityRepository for managing customer plans and associated facilities.
- Removed PlaceService and its related methods, consolidating functionality into FacilityService.
- Added RfidTagService for managing RFID tags, including methods for creating, updating, and setting statuses of tags.
- Updated TenantDbContext to include new DbSet for RfidTags and CustomerPlanFacilities, and adjusted model configurations accordingly.
- Enhanced FacilityService to support new booking modes and validation for facility creation and updates.
