Fix integration test failures

- Fix test_data_file_db_sync.py: Remove unused mock logger parameters
- Fix test_nfo_workflow.py: Add missing async mocks for TMDB methods
  * Add get_tv_show_content_ratings mock for FSK rating support
  * Add get_image_url mock to return proper URL strings
  * Fix test_nfo_update_workflow to include TMDB ID in existing NFO
- Fix DownloadService method calls in test fixtures
  * Change stop() to stop_downloads() (correct method name)
  * Change start() to start_queue_processing()
  * Add exception handling for ProgressServiceError in teardown
- All 1380 tests now passing with 0 failures and 0 errors
