Stabilize feed order with a deterministic signal-score tiebreaker

Browse Source 
Equal-score stories reshuffled on every pull-to-refresh because the sort
was unstable. Add StorySummary.feedOrder (signalScore desc, then id desc,
mirroring the backend's signal_score DESC, id DESC) and use it for the feed,
the WebSocket re-sort, and the Saved/Search tabs.
