feat(editor): scatter texture patches for natural surface variety

Browse source 
- Scatter Patches: randomly places texture circles across the terrain
  for natural-looking surface variation (dirt patches, rock outcrops)
- Configurable count, min/max radius, and seed
- Preset buttons for dirt and rock patches
- Uses the existing paint() method with random positions
- Adds visual variety to otherwise uniform terrain texturing
