f.date/f.ago assumed JS milliseconds, but the backend emits Unix epoch
seconds everywhere (created_at, feed lastUpdate, rule lastMatch, …), so
every real timestamp rendered as ~20607 days ago (now - ~1.78e9 ms).
Treat the formatter input as seconds. Search results show the indexer's
pubDate string directly rather than mis-parsing it.
