fix(locallibrary): track-row source indicator (drop fav/offline) + AlbumView favorite item

LocalLibrary track rows (Tracks tab + local album detail) no longer carry the
favorite or offline-cache columns — they don't apply to local content. Instead
they show a subtle per-source indicator (local -> hard-drive tinted; qobuz
offline / plex -> their mark), small + flat rather than the bold album-card
badge (mirrors Tauri's track-row local indicator). TrackItem gains a `source`
field, set by every constructor (Qobuz surfaces -> "qobuz"; map_local_track ->
local/qobuz/plex); TrackRow gains `show-source`.

Also fixes Qobuz AlbumView: the track list had a Favorite column header but the
rows never rendered the heart (show-favorite defaulted false). AlbumPageView
now sets show-favorite + show-download for Qobuz albums (matching the header)
and the source indicator for local albums, with the column header switched to
match each.
