The favorites-labels wire item (LegacyLabelDto) carries an `image`
field that FavLabel silently dropped, so label cards had no artwork.
Parse it (bare string or the object form, via label::extract_label_image),
plumb it onto LabelCard + FavoriteLabelItem, and issue a FavoriteLabel
artwork job + apply arm mirroring favorite artists. Align the count line
to "{n} albums" (matches Tauri and the sibling artist card) and seed
labels-visible for the upcoming search filter.
