feat(editor): quick biome paint presets (6 biomes, one-click full texture)

Browse source 
- Quick Biome Paint: select a biome (Grassland/Forest/Desert/Snow/Swamp/Barrens)
  and apply its full texture set in one click
- Sets base texture for all chunks + scatters variation patches
- Each biome has a primary ground texture + secondary variation
- Much faster than manual painting for initial zone texturing
