Rebuild ansible on the project deploy template

- playbook.yml (hosts: monoco) + vars/default.yml, requirements.yml
- roles: network (shared docker network), greatbear (registry pull,
  bind mount /var/lib/greatbear/pb_data, .env upload, health wait),
  caddy (blockinfile snippet into the shared Caddyfile + docker exec reload)
- image honors PB_DATA_DIR and runs as root to match the bind-mount pattern
- frontend on www.greatbear.in (+apex) with /api/* and /_* proxied to
  PocketBase; admin.greatbear.in redirects to the admin UI
