Set weekly Saturday 7AM on-call rotation config entry

Your on-call rotation value can drift and cause pages to reach the wrong engineers and delaying incident response. It sets the rotation key so paging and handoffs remain correct before weekend coverage.

Overview

Weekend paging errors often stem from stale rotation settings that route alerts to the wrong engineers and slow response. This scheduled shift setter updates the rotation key at 7am Saturday so routing and handoffs are correct before weekend coverage, reducing confusion and response time.
