fix(web): de-overlap Most Played hover controls + narrow desktop seek bar

CompactTrackCard is a short one-line row but reused CardActionCluster,
which corner-splits Like+Add (top) and the kebab menu (bottom). That split
is right for the tall square Album/Artist cards but makes the two groups
collide on the compact row's hover state. Give the compact card a single
inline, vertically-centred right cluster (Like + Add + menu in one group)
and widen its right padding reserve to match.

In the desktop PlayerBar, the left info column was a fixed w-72 (title kept
truncating) while the seek column was flex-1 (the scrubber hogged the slack
on wide screens). Let the left column grow up to max-w-md while holding its
288px floor at md, and cap the seek/transport column at max-w-xl centred, so
freed width flows to the title instead of stretching the bar.
