- Created ScontainersRepository for database interactions, encapsulating logic for container management.
- Updated container edit and list views to utilize new templating system.
- Added unit tests for ScontainersRepository and ScontainersController to ensure functionality.
- Enhanced form handling for container editing, including validation and error management.
