Auto: replaced 'Manual all' + 'Auto all' (which fired auto on every source = up to
one download PER source = duplicate copies) with a single header 'Auto' button. It
searches every source, waits for them all to settle, compares the accepted+grabbable
hits across ALL sources by quality-profile score (tie-break on availability), and
grabs exactly ONE winner — the chosen row gets the auto ring + live tracker. Per-source
Manual/Auto buttons are unchanged.
Bug fix: viewing a YouTube channel populated the playlist section in the SHARED
show-detail DOM; opening a real movie/show afterward still showed those playlists,
because ytResetPlaylists() used the kind-scoped q() (pointing at the wrong root on a
movie load) and wasn't called on normal loads. Now it targets the show subpage
directly and runs from resetExtras() (every detail load), so stale playlists are
always cleared.
node --check clean; 20 wiring/regression tests green; all video-only.
