maj00r ddb637a3f5 feat(editor): undo and redo take back the kept alignments and switches together with the paths: each step of the history keeps the //$h and //$r records from before it; a deleted switch or slip forgets its record in the same step, so undoing the deletion brings it back; edits of the switch number, rail and km and forgetting a kept design stay outside the history; self-test commands deleting paths
