fix: Update test fixtures to use correct service method names

- Fixed test_download_progress_websocket: stop() -> stop_downloads()
- Fixed test_download_service: start() -> initialize(), stop() -> stop_downloads()
- Resolved 8 test errors and 3 test failures
- Test status: 970 passing, 31 failing (down from 967 passing, 34 failing, 8 errors)
- All 104 NFO-related tests still passing (100%)
