Integrate Deezer download source into orchestrator

Added deezer_dl to all orchestrator methods: init, is_configured,
get_source_status, check_connection, search (single + hybrid), download,
get_all_downloads, get_download_status, cancel_download, clear_completed,
cancel_all, and reload_settings. Full parity with existing 5 sources.
