fix: resolve event deletion 500 error with proper foreign key handling

- Rewrite delete endpoint to use database transaction
- Delete related data in correct order: access_logs, email_queue, photos, photo_categories, then event
- Add cleanup for storage folders and archive files
- Improve error messages for better debugging
