Phase 10-08: Implement DNS egress NetworkPolicy for staging environment

- Add comprehensive network policies to k8s/staging/network-policy.yaml
- Implements default-deny ingress pattern with explicit allow rules
- Critical: Add DNS egress rule for CoreDNS resolution (port 53 UDP/TCP)
- Policies cover: ingress-nginx→backend, backend→postgres, monitoring scrape
- External API egress for backend (HTTP/HTTPS)
- CDN egress for frontend (HTTP/HTTPS)
- Status: Applied to gravl-staging namespace, verified operational
