fix: backgammon UI — checker stacking, dice classes, board proportions

- Wrap checkers in .bg-checkers-stack div for proper flex stacking
- Fix dice class names (bg-die → bg-dice) to match CSS
- Fix player info class names to match page HTML
- Make board taller (aspect-ratio 1.2/1), checkers smaller (32px)
- Fix borne-off tray positioning
- Add result overlay styles
