PlaylistTrack.streamUrl is String? (nullable when track is unavailable
post-delete); TrackRef.streamUrl is required String. flutter analyze
caught the mismatch. Coalesce to empty string for unavailable rows —
they're already filtered out by the trackId != null check earlier in
the loop, so this branch is effectively unreachable but keeps the
type-checker happy.
