Reduce PodNotReady alert lookback from 5m to 60s

Browse source 
The 5-minute lookback window kept stale data from terminated pods
visible during rollouts, causing the alert to sit in Pending for
~5 minutes after every routine deployment. 60s still covers two
scrape cycles (30s interval) while clearing stale data much faster.
