Validate uniqueness of invitation codes during guest creation to prevent duplicates. Automatically generate an 8-character code if none is provided, ensuring consistent data handling. Updated tests and schemas to support these changes.
Introduce a new API for managing event guests, including endpoints for creating, reading, updating, deleting, and changing guest status. Added corresponding Pydantic schemas, database CRUD logic, and extensive test coverage to validate functionality. Integrated the guests API under the events router.
