feat(editor): smooth entire tile, snap-to-ground toggle, object list improvements

Browse source 
- Smooth Entire Tile: global smoothing pass with configurable iterations
  (1-10). Smooths across chunk boundaries for seamless results. Updates
  inner vertices from smoothed outer grid. Great after noise generation.
- Snap to Ground checkbox: on by default, objects placed at terrain
  surface. Disable for floating/airborne objects.
- Random Rotation + Snap Ground checkboxes side-by-side for fast setup
- Toast notifications on noise apply and smooth operations
- Smooth pass uses cross-chunk neighbor averaging for edge continuity
