refactor: remove MinIO repository references and streamline cleanup process

- Eliminated MinIO repository dependencies from the `Activities`, `Cleanup`, and `Training` classes.
- Updated the `cleanup_resources` method to focus on removing local temporary directories instead of handling MinIO file deletions.
- Adjusted the `TrainModel` class to pass the run directory for cleanup, enhancing resource management in the training workflow.
