fix(home): match Figma media pills for latest cards

- Align latest-update media size pills to the Figma spec: 72x24 pill, black background, 24px gray icon cell, 10px label, and the exact small Figma cloud-download SVG.
- For non-document latest cards, remove the duplicate footer download action so media cards only show per-media size/download pills plus the bookmark action, matching the Figma non-document card design.
- Keep card heights flexible so content determines the final card height instead of locking to design mock heights.
