ui(uxp): v2.2.0 — density pass: drop details panel, tighter buttons, collapsible Advanced

User feedback after v2.1.9: panel still chrome-heavy. The Asset Info
panel duplicates what the card already shows; 8 buttons across 3
full-width rows still claim too much vertical real estate.

Three surgical changes:

1. Drop the Asset Info details panel entirely. Card meta (name +
   duration + codec) already carries everything we showed in the
   key:value table. Library._showDetails / hideDetails become no-ops
   so the existing call sites in main.js + library.js don't need
   conditional branches.

2. Shrink .action-row .btn to 20px tall, 10.5px font, 6px horiz
   padding, 3px radius. Two rows of compact buttons fit where one
   bulky row used to.

3. Collapse Advanced section behind a toggle (▸ / ▾). Default
   collapsed so the main 6 buttons stay the primary action surface;
   click the row to expand and reveal Export & Conform / Fetch &
   Relink All.

Per DESIGN.md "density over whitespace."
