Center SaveCachedPose node in view when navigating from UseCachedPose

Browse Source 
When double-clicking a UseCachedPose node to jump to the SaveCachedPose
node's tab, the view now centers on the target node. Added CenterOnNode
helper that adjusts TranslateTransform to place the node at the viewport
center while preserving the current zoom level.
