Prevent duplicate ticket alerts for operations staff now

Operations coordinators see notified-email lists pile up, causing stale flags that block ticket alerts. An hourly cleanup clears stored notified emails so alerts don't repeat.

Overview

Stale notification caches cause duplicate alerts and blocked tickets, creating operational confusion and slower handoffs. A scheduled hourly cleanup clears the notified-email cache so alerts fire correctly and operations avoid repeat notifications.
