fix(editor): normal recalculation after sculpt, mode switch cleanup

Browse source 
- Terrain normals recalculated after height changes (smooth lighting
  on sculpted terrain instead of flat-shaded appearance)
- Ghost preview and brush indicator cleared when switching modes
  (prevents stale model instances or circles persisting)
- File > Clear All resets undo history and selections
- Normal computation uses finite differences from neighbor heights,
  handles both outer (9x9) and inner (8x8) vertex grid positions
