feat: full backgammon overhaul — 60fps game loop, premium canvas, particles, admin branding

- 60fps requestAnimationFrame game loop with dt-based particle physics
- 3D checkers with radial gradients, specular highlights, drop shadows
- Wood-grain board texture with gradient triangles and bevel frame
- Physics-based dice with bounce damping, spin, and staggered animation
- Arc-based move animations with easeOutBack overshoot
- Particle burst on hit (red/orange sparks) and bear-off (green stars)
- Confetti celebration on match win with canvas animation
- Full multiplayer sync via match-session + server polling
- Bot AI with animated moves (arc + SFX per piece)
- Admin branding: 14 board colors + 7 game settings (durations, particles)
- CSS tokens for all backgammon board colors (--bg-*)
- Theme.js maps branding values to CSS vars + window.__EL3AB_THEME
