quickshell: poll k8s metrics only while the popout is open

The metrics poller spawned the heavy k8s-metrics script every 15s all day
even though its data only renders in the popout. Gate it on the popout
being open (triggeredOnStart fetches immediately on open) and slow the
pill's status poll from 30s to 120s.
