fix: Complete SQLAlchemy 2.0 migration - add session parameters to all controller calls

- Add session parameter to all view functions and controller calls
- Fix pipeline files to use get_session_factory() for background tasks
- Update PipelineMainBase and PipelineMainFile to handle sessions properly
- Add missing on_* methods to PipelineMainFile class
- Fix test fixtures to handle docker services availability
- Add docker_ip fixture for test database connections
- Import fixes for transcripts_controller in tests

All controller calls now properly use sessions as first parameter per SQLAlchemy 2.0 async patterns.
