Update GUI state in resetToDefaults

suppressReload was eating the file-watch callback that would have
called loadConfig and refreshed the draft from disk, so the GUI stayed
on the pre-reset layout even though bar.json was already correct.
Apply the reset payload directly to draft (and bump draftRevision) so
section editors re-render in the same frame.
