test: add comprehensive test suite for QobuzDownloadService
- Add 15 unit tests covering authentication, download logic, and configuration - Test IsAvailableAsync with various credential combinations - Test download flow for unsupported providers, existing files, and missing songs - Test album background download functionality - Test quality format configuration (FLAC, MP3, default) - All tests passing (127 total tests)
