feat: Add entity.grid property and fix auto-removal bug

UIEntity now has a `.grid` property with getter/setter:
- entity.grid          # Get current grid (or None)
- entity.grid = grid   # Move to new grid (auto-removes from old)
- entity.grid = None   # Remove from current grid

Also fixes UIEntityCollection.append() to properly implement the
documented "single grid only" behavior - entities are now correctly
removed from their old grid when appended to a new one.

This matches the parent property pattern used for UIDrawables.
