Note

Low Risk
Low risk: adds a new Prometheus histogram and wires it into NetworkMetrics for the benchmark node, without changing networking behavior or data handling.

Overview
Adds a ping_latency_seconds histogram metric to the broadcast network stress test node and wires it into the exported apollo_network::metrics::NetworkMetrics via LatencyMetrics (previously latency_metrics was None). This enables the benchmark to record and export ping latency alongside existing broadcast/SQMR/event metrics.
