quickshell: speed up k8s refresh while the popout is open

While the popout is open, poll both status and metrics at a fast cadence
(kubeRefreshOpenMs, 3s) instead of 2min/15s, and refresh immediately when
it opens — so opening the pill shows fresh data and updates live. Status
reverts to the slow 2min pill cadence once closed.
