feat(editor): random rotation, placed object list, quality of life

Browse source 
- Random Rotation checkbox: each placed object gets a random Y rotation
  (great for natural-looking tree/rock placement without manual tweaking)
- Placed Object List: collapsible list in Object panel showing all placed
  objects with name and position, click to select
- Both features reduce repetitive manual work when building dense zones
