feat(deploy): Docker Compose stack for the instance
Caddy, the Serverpod server and PostgreSQL 16 in deploy/. Only Caddy publishes ports; the server and Postgres are reachable only inside the Compose network (Docker bypasses ufw, and the server listens on every interface). Secrets come from deploy/.env as environment variables; there is no production passwords.yaml, and .dockerignore keeps local secrets out of the build context.

The server image builds on Serverpod's template with an Ubuntu 24.04 runtime: complete glibc incl. libgcc_s for the SQLite libraries Serverpod 4 bundles, CA certificates, a non-root user, and exec so SIGTERM reaches the server. The scaffold's dev-only docker-compose.yaml is removed.

Verified locally: image builds, all native libraries resolve, no passwords.yaml in the image, migrations apply at start, Caddy serves 200, port 8080 unreachable from the host, Postgres in UTC.
