fix: clear pending undo debounce timer on loadWorkflow and clearWorkflow

If a debounced data-edit snapshot was pending when loading or clearing
a workflow, it could fire after undoManager.clear() and push stale
state into the new workflow's undo history. Now both paths cancel the
pending timer and snapshot before clearing.
