Fix Navidrome incremental update to use getAlbumList2 API for recent albums

Summary: Navidrome incremental updates always found 0 new tracks because _get_recent_albums_navidrome() fetched all artists, sampled only the first 200, collected their albums, and sorted by created date — missing artists beyond the first 200 entirely. Replaced this with a single getAlbumList2?type=newest Subsonic API call that directly returns albums sorted by library addition date, matching how Jellyfin and Plex already use their native "recently added" endpoints.
