- usePolling gains a pauseWhenHidden option (default true): the timer
pauses while the document is hidden (background tab / minimised) and
resumes with an immediate reload on returning to visible. Callers keep
owning their initial fetch, so no duplicate first request.
- CronPoolMonitor now delegates its 5s poll to the shared usePolling hook
(initial load stays in its own useEffect); removes the bespoke
setInterval + manual visibility gap.
- CronPoolMonitor.test: visibility guard now passes (3/3), removing the
previous it.fails. Frontend suite: 18/18; tsc clean; backend 878.
