Emi Griffith 47aea569ed Add Terraform to provision the VPS hosts (compose keeps running the app) (#223)
Terraform config under terraform/ manages the two existing VPS hosts and hands the
app to docker-compose, with local state:

- prod: the new 48GB/12-core VPS (release branch, thermograph.org), sized larger.
- beta: the old VPS 75.119.132.91 (main branch, testing tier), no public domain.
- The LAN dev box stays on deploy/deploy-dev.sh (dev branch) — out of Terraform.

A reusable module (modules/thermograph-host) SSHes each host to install docker/
compose/ufw (+ Caddy when a domain is set), sync the checkout to the host's branch,
render /etc/thermograph.env from Terraform variables (secrets pushed via provisioner
content, never on local disk), `docker compose up -d`, and health-check. Named
volumes are preserved on re-apply, so the Postgres data is never recreated.

Container resources are now env-driven in docker-compose.yml (APP_CPUS/DB_CPUS/
DB_MEMORY/WORKERS) with unchanged defaults, so Terraform can size each host.
