Refactor Catalog API: Remove Create Catalog Item Endpoint and Update Related Logic

- Removed the "Create Catalog" endpoint from the Postman collection.
- Updated the CatalogController to handle tenant-specific catalog items based on active events.
- Refactored CatalogItem model to automatically set event_id based on tenant's active_event_id during creation.
- Deleted StoreCatalogItemRequest and CatalogItemResource as they are no longer needed.
- Updated various services and controllers to utilize the new tenant-based catalog item retrieval logic.
- Added tests to ensure that catalog reads are limited to items associated with the active event.
