Clean up actor editor branch: DRY, dead code, CSS

- Extract buildNodeToPartGroupMap() in ActorRenderer to deduplicate
  map-building logic in loadAnimationForActor and playClickAnimation
- Refactor updateMissionScore() to use getMissionScoreOffset() instead
  of duplicating offset calculation
- Remove unused ActorPartLabels export from actorConstants
- Make fetchBitmap module-private (only used by fetchBitmapAsURL)
- Merge duplicate .globe-btn CSS blocks in LightPositionEditor
