fix #2: header pill refreshes itself after swipes, undo and new batches

loadStats() only ran once at boot, so the live/fresh/new pill (and the
list sub-line) went stale until a full reload. Refresh it, debounced and
fire-and-forget, after any decision change, when a new batch lands, and
on app foreground. Adds two fe_walk_v11 regression checks + a UI-SPEC note.
