fix(queue): marquee long track names + dedupe now-playing bars

Queue sidebar no longer scrolls horizontally on long titles/artists:
text now ping-pong scrolls (news-ticker style) only when it overflows,
via a new Marquee component; .qd-scroll also clips overflow-x.

The current track previously showed the playing-bars indicator both in
place of the drag grip and over the cover. Keep only the cover overlay
and restore the drag grip on the current row.
