Resi: checks keep quiet while a Resi event starts or stops (weekly schedule + PCO special services)

User 2026-10-26: three services each have a Resi event that starts and stops on its own; the cloud,
decoder and Resi audio checks threw false alarms then. resi_events (weekly, from studio.resi.io) and the
special services' times from PCO; checks marked quiet resi_events show OK (EVENT CHANGE) within 10 min of
an event's start or end. The encoder's ping and web checks still alarm.
