Add migrations for ParkPhoto and RidePhoto models with associated events

- Created ParkPhoto and ParkPhotoEvent models in the parks app, including fields for image, caption, alt text, and relationships to the Park model.
- Implemented triggers for insert and update operations on ParkPhoto to log changes in ParkPhotoEvent.
- Created RidePhoto and RidePhotoEvent models in the rides app, with similar structure and functionality as ParkPhoto.
- Added fields for photo type in RidePhoto and implemented corresponding triggers for logging changes.
- Established necessary indexes and unique constraints for both models to ensure data integrity and optimize queries.
