Allow Docker to distinguish a running container from one actually serving traffic by adding a /health endpoint that pings the database. Returns 200 when healthy, 503 when the DB connection is lost. Add HEALTHCHECK to Dockerfile and healthcheck config to the server service in docker-compose.yml. Also add start_period to the existing db healthcheck for consistency.
