rblundon 881e2e24a8 Add shared nginx-proxy role; deploy Hermes in Docker; rename Paperclip
nginx-proxy (new role):
- Shared nginx + certbot under /opt/nginx, replacing the copies that
  lived inside the Paperclip compose project
- Apps publish via tasks_from: add_vhost (cert marker -> issue cert ->
  write vhost -> nginx -t -> reload); a vhost that fails nginx -t is
  rolled back
- Certs issued one per domain via Cloudflare DNS challenge; domains
  registered as marker files in cert-domains/; optional LE staging
- Stock nginx.conf plus conf.d (directory mounts, not single-file
  mounts); catch-all server drops unknown Host/SNI
- Containers renamed to nginx and certbot

hermes_docker (new role):
- Official Hermes image, host networking, gateway and dashboard bound
  to loopback and published through nginx-proxy
- Dashboard login via basic-auth provider, secrets from the vault
- Main model set from hermes_model (fantasmic endpoint, key from vault);
  config.yaml overrides are merged from a 0600 staged file that is
  removed afterwards, so the key never appears in a command line
- Data dir owner-only (HERMES_HOME_MODE=0700)

paperclip-docker:
- Remove nginx, certbot and docker-compose download tasks; deploy with
  community.docker.docker_compose_v2 (idempotent, remove_orphans)
- Stop passing the Cloudflare token and certbot email to the Paperclip
  container via env_file
- Bind Postgres to 127.0.0.1 (host networking exposed it on all
  interfaces); stop chowning pgdata, which the postgres image owns
- Handler recreates the paperclip service so .env changes apply
- Domain m-v.wdw-labs.cloud -> cranium-command.wdw-labs.cloud

Playbooks:
- Add day1_deploy_nginx_proxy.yml and day1_deploy_hermes_docker.yml
- deploy_paperclip_stack.yml: run nginx-proxy before paperclip-docker,
  CLI-based container checks (no Docker SDK dependency)
- Remove deploy-hermes.yml

Host vars: add nginx_proxy_certbot_email and nginx_proxy_certbot_staging
(staging stays on until the switch to real certs).
