Subject: [PATCH] Center SaveCachedPose node in view when navigating from
 UseCachedPose

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.
