Durations of running builds are ticked client-side, so a page left in the background kept counting up a build that had long finished on the server — on a phone the tab is frozen for an hour and comes back showing a build "running" for an hour. Resuming now re-arms the poll unconditionally instead of only when the page was stopped: a frozen page may never deliver the hidden event, and its throttled interval then fires whenever the browser feels like it. `pageshow` and `focus` are listened to as well, because not every browser reports a returning page as a visibility change; resume events arriving together are collapsed into one fetch. Verified in a browser: hidden for 11s over a 10s interval makes no request, a lone focus event makes exactly one, and a second resume event right after makes none.
