feat(ansible): idempotent role-based host config for both production VMs

common/firewall/docker-tls/platform/lab-host/monitoring-agent/backup roles, orchestrated by site.yml with the ordering that matters (firewall/TLS land before the services that depend on them). Ansible Vault for secrets, no new tool introduced for this project's modest secret surface. Explicit dev/staging/production environment separation, no secrets committed (.gitignore covers vault plaintext, TLS keys, Terraform state, *.env). Validated: ansible-playbook --syntax-check clean.
