Replaced complex react-spring + useDrag implementation with simple
PointerEvents-based drag and drop:
- Uses native onPointerDown/Move/Up events
- Tracks position with useState (no animation library)
- Cards stay exactly where dropped (no physics or snap-back)
- Simple scale-up effect while dragging
- Much more predictable and maintainable
Removed dependencies on:
- @react-spring/web
- @use-gesture/react
- Complex velocity tracking and decay physics
- Transform-origin calculations
