refactor(cra): prioritize reference_id for job deletion in DeleteMediaJob

- Adjust logic in DeleteMediaJob to prefer reference_id for deleting jobs, ensuring all phase jobs are removed when available.
- Maintain functionality for direct job deletion using id if reference_id is not present.
- Improve logging for job deletions to enhance traceability.
