Center-zone pane drag swapped dragged.draft/target.draft but left draftForms cached under the old leaf id, so both panes kept showing their pre-swap form values while writing into the swapped leaf. Tear down both leaves' cached forms at swap time (same pattern as openDraft's stale-form teardown, #72) so render() remounts fresh forms seeded from the swapped data. Fixes #73
