Add convenient port-forward targets for Prometheus monitoring

Added enhanced port-forward targets with helpful UI information:
- 'just alerts' - Quick access to Prometheus alerts view
- 'just alertmanager' - Quick access to Alertmanager UI
- Enhanced output showing all relevant URLs

All port-forward commands now display:
- Access URLs with direct links to specific views
- Clear instructions for stopping (Ctrl+C)

Usage:
  cd prometheus/
  just alerts              # Opens Prometheus alerts (port 9090)
  just alertmanager        # Opens Alertmanager (port 9093)
  just port-forward-prometheus [port]
  just port-forward-grafana [port]

After running, access:
- Prometheus Alerts: http://localhost:9090/alerts
- Alertmanager: http://localhost:9093
