Denis Groshev e95ae7b80c Keep the news layer inside its day and its memory bounds
From review of the news layer:
- An event's other sides older than 24 hours (or undated) are no longer
  listed, and a report dated more than 15 minutes ahead is outside the
  window, as in the regional brief.
- Picture cards are one canvas per event in a bounded cache (24), repainted
  in place when the age changes, with each card's picture dropped with it;
  the age in the key had made a new canvas every minute.
- The feed list drops reports that leave the window and is capped at 600.
- "In view" is filtered from the reports the layer already holds; it reads
  the feed only with minor news on, once per refresh, never per pan.
- Infinite scroll restarts after a filter change or a failed read.
- The two filter selects stack, so "Significant and above" is not cut off.
- The timeout tests hold the event loop until aborted, so they pass on
  Node 22 as well.
