feat(editor): zone map image export (colored top-down PNG)

Browse source 
- exportZoneMap(): renders terrain as colored top-down image with
  height-based coloring (blue lowlands → green plains → brown hills →
  white peaks), water overlay, hole visualization, doodad markers
- Configurable resolution (128-2048px, default 512)
- Auto-exported as zone_map.png alongside other assets on save
- File > Export Zone Map menu with resolution slider
- Useful for documentation, server admin tools, custom map websites
