- IPS_Editor_ChildMovable gains GetChildRotation / RotateChild and the
GetAll/SetAll rotation pair for undo snapshots. BP impls can clamp axes
(e.g. Yaw-only) inside RotateChild.
- Pawn captures initial rotations at gizmo drag start and applies the
rotate gizmo's delta-quat onto the active child only (no longer
rotating every selected actor when a child handle is active).
- FPS_Editor_SplinePointAction carries optional Old/NewRotations arrays
applied alongside positions on Undo/Redo for ChildMovable actors.
- Pawn now calls ClearChildHighlight before HighlightChild so picking a
new child no longer leaves the previous one stuck in highlight state.
- MainWidget + Legacy widget detect when ActivePlacementActor is a
ChildMovable in SplinePlacement mode and swap the help bar text
("CHILDREN: ...") + hide the irrelevant Delete-point button.
