Architecture:
- New IPS_Editor_PointPlaceable interface for any actor using click-to-place-
points placement. Decouples the placement system from SplineActor so future
actors (patrol routes, area polygons) can reuse the same flow.
- SplineActor implements the interface. BP subclasses with SpawnableComponent
appear in the catalog and automatically enter placement mode when spawned.
- PlayerController methods renamed: BeginPointPlacement/FinishPointPlacement/
CancelPointPlacement (generic, interface-driven).
Features added:
- SplineColor, SplineSelectedColor, SplineTag as UPROPERTY for BP overrides
- UpdateSplineMaterials() for runtime color changes
- Tube visualization (8-segment cylinder) replacing cross-ribbon
- Spline editing mode with Edit/Done buttons in notification bar
- Delete spline point (Del key or Delete Point button, min 2 points)
- Insert point by clicking on tube mesh in edit mode
- Snap spline point to ground (End key)
- Append points to existing spline (S key or catalog when spline selected)
- Notification bar: contextual messages and buttons per mode
- Auto-generated M_PS_Editor_SplineLine material (unlit opaque, depth tested)
- Material swap: opaque when deselected, no-depth-test when selected
- Serialization of SplineColor/SplineTag in CustomProperties
