fix(stacked-note): act on outdated badge clicks

Clicking the badge while it shows outdated now pulls the latest version
from GitHub when there are no unsaved edits, or opens the conflict
modal when edits are in flight. Previously the click only re-ran the
same freshness check, so the badge appeared dead.
