Backfill album release_date from stream tags when T2Tunes metadata omits it

Browse source 
T2Tunes albumList entries may not include a release_date field, leaving the
$year path template empty. get_album() now falls back to the first track's
release_date (populated from the FLAC date tag via get_album_tracks) when
album metadata has none. Also try camelCase releaseDate key at all albumList
read sites (Album.from_metadata, get_album, _fetch_album_metas consumers).

1 new test: release_date backfilled from stream date tag when absent from
album metadata. date tag "2024-11-22" added to MEDIA_RESPONSE_FLAC fixture.
