Rotation gizmo:
- Quarter-arc rings via UProceduralMeshComponent (3D solid with depth)
- Dynamic arc facing: arcs flip to face camera based on octant
- Grey guide lines from center to arc endpoints
- Screen-space rotation direction (correct from any camera angle)
Scale gizmo:
- Arrow shafts + cube tips for per-axis scale
- Center cube (grey) for uniform XYZ scale
- Local space orientation (gizmo aligns with actor rotation)
Other:
- Runtime confirmation dialog (replaces FMessageDialog)
- ProceduralMeshComponent plugin dependency added
