AppConfig Persistence Fixes:
- Fix constructor to properly handle null localStorage values
- Add null check before JSON.parse to prevent errors
- Create fresh config copies with spread operator to avoid reference issues
- Add better error handling and logging for config loading
- Initialize handles array properly
React ConfigModal Improvements:
- Fix config initialization to get fresh values on render instead of stale module-level values
- Separate useEffect hooks for each config property (prevents unnecessary updates)
- Fix SegmentedControl string-to-number conversion (locationSnaps now use "0.01", "0.1" format)
- Enable/disable logic now properly sets values to 0 when disabled
Handle Storage Consolidation:
- Create dynamic HandleConfig type with Vec3 for serializable position/rotation/scale
- Add handles array to AppConfigType for flexible handle storage
- Replace individual localStorage keys with centralized AppConfig storage
- Add handle management methods: getHandleConfig, setHandleConfig, removeHandleConfig, getAllHandleConfigs
- Update Handle class to read from AppConfig instead of direct localStorage
- Update dropMesh to save handles via AppConfig using Vec3 serialization
- Convert between BabylonJS Vector3 and serializable Vec3 at conversion points
Benefits:
- Single source of truth for all configuration
- Proper localStorage persistence across page reloads
- Dynamic handle creation without code changes
- Type-safe configuration with proper JSON serialization
- Consolidated storage (one appConfig key instead of multiple handle-* keys)
