feat(editor): auto-paint terrain by height bands

Browse source 
- Auto-Paint by Height: automatically sets base texture per chunk based
  on average height — configurable thresholds for sand/grass/rock/snow
- Uses Tanaris sand, Elwynn grass, Barrens rock, Dragonblight snow
- One-click to texture an entire procedurally generated terrain
- Adjustable height thresholds via drag floats
- Workflow: noise → smooth → clamp → auto-paint for instant biome
