feat(databases): enhance backup update and deletion logic with validation

- Added authorization checks for updating and deleting backups in DatabasesController.
- Implemented validation for S3 storage UUID when saving backups, ensuring it belongs to the current team.
- Improved error handling during backup deletion with transaction management for better data integrity.
