Spawn actor at location with rotation

Pattern: MakeTransform(Location=SpawnLocation, Rotation=SpawnRotation, Scale=(1,1,1)) → SpawnActorFromClass(Class=ActorClass, SpawnTransform=Transform) → CastTo<YourClass>(ReturnValue). SpawnActorFromClass inputs: 'ActorClass', 'SpawnTransform' (Transform), not separate Location/Rotation. Use MakeTransform node to build the Transform struct from Location+Rotation+Scale.
