PR Summary

Low Risk
Single config key moved to a shared overlay; no application logic or security behavior changes.

Overview
Centralizes hybrid sequencer monitoring configuration by setting monitoring_endpoint_config.port to 8082 in the shared hybrid/common overlay, aligning it with the existing monitoring-endpoint service port and metrics/probe paths.

Per-environment hybrid overlays no longer need to duplicate this setting (removed in the paired devops PR).
