Update daily group chat labels for pending checks

You rely on group chat threads for support and ops; unmarked threads delay triage and obscure priority. Labeling creates a prioritized queue so staff can act same day.

Overview

Untagged chat threads create hidden backlog and slow triage; a daily scheduled run converts chat volume into a clear, actionable queue. This lets support engineers and program coordinators start checks and resolve items same day, preventing next‑day pileups.
