Use Unicode NFD decomposition to strip combining marks so variants like
"Özkent" and "Ozkent" are treated as equivalent. Apply the new helper
in both tidal.go and qobuz.go artistsMatch functions.
SongLink can return incorrect track IDs (e.g. a different track from the
same album). Qobuz already had verification via qobuzTrackMatchesRequest.
This adds equivalent verification for Tidal and Deezer using a shared
trackMatchesRequest() helper in title_match_utils.go that checks artist,
title, and duration. Mismatched SongLink/ISRC results are now rejected
so the wrong audio is never embedded with Spotify metadata.
