fix(editor): camera auto-centers on actual terrain chunks after ADT load

Browse source 
- Camera now positions at the center of actual loaded terrain chunks
  instead of using formula-based coordinates that can be wrong for
  instanced maps
- Falls back to formula if no valid chunks loaded
- Fixes camera starting far from terrain on some maps
