Fix mobile animation card sizing and layout polish

- Fix animation overlay cards rendering at wrong size: base .card CSS
  (clamp 65px min) was overriding the inline dimensions set by JS.
  Add !important to .draw-anim-front/.draw-anim-back width/height: 100%
  so overlays always match their parent container size.
- Size opponent swap held card to match opponent card dimensions instead
  of defaulting to deck size (looked oversized on mobile)
- Shrink dealer chip on mobile (38px -> 20px) to fit opponent areas
- Make header more compact: smaller fonts, tighter gaps, nowrap on badges
- Bump deck/discard to 72x101px to match player card size on mobile
- Add spacing between header/opponents, and between deck area/player cards
