Forward incoming webhook messages to callbacks and log metrics

Inbound messages lack centralized forwarding and visibility, delaying triage for ops. It forwards messages and logs delivery metrics so ops can spot failures and act same day.

Overview

When inbound messages aren't forwarded and monitored, triage stalls and SLAs risk slipping. Centralizing forwarding plus attempt/success metrics gives ops and support immediate delivery visibility so failures are detected and resolved the same day.
