feat(editor): minimap camera indicator, bulk operations, snap all

Browse source 
- White crosshair on minimap shows camera position in real-time
- Bulk Operations section in Object panel:
  - "Delete All in Radius": removes all objects within brush radius
  - "Snap All to Ground": raycasts every object downward to terrain
    (fixes all floating objects in one click)
- Minimap legend updated with camera indicator
- Useful for cleaning up scattered objects or fixing placement height
