devops(observability): fix Prometheus port binding, scrape port, and update DEPLOYMENT.md
- Fix spring-boot scrape target from backend:8080 to backend:8081 (actuator/management port)
- Restrict Prometheus host port binding to 127.0.0.1 to prevent unintended external exposure
- Add observability stack (Prometheus, Node Exporter, cAdvisor) to topology description
- Add PORT_PROMETHEUS env var to DEPLOYMENT.md reference table
