fix: probe alignment across multiple monitoring contracts

- infra-monitoring: Added Router+LiteLLM+PVE API probes with expected HTTP codes (200/401/500)
- gpu-monitor: Added explicit check-health section with Router+LiteLLM probe commands
- proxmox-monitor: Added check-health section for Prometheus/Grafana/exporters (all bound to 0.0.0.0)
- zulip-health: Fixed A2A port from :8001 to :50080 and added auth-gated expectation (401)

Closes: infra-monitoring-probe-alignment, gpu-monitor-probe-alignment, proxmox-monitor-probe-alignment, zulip-health-probe-alignment
