Subject: [PATCH] devops(docker): add healthchecks for db and api services
 (#10)

- Add pg_isready-based healthcheck for the db (postgres:16-alpine) service
  so depends_on waits until Postgres is ready to accept connections, not
  just until the container has started.
- Add curl /health-based healthcheck for the api service using the
  existing GET /health liveness probe.
- Upgrade depends_on: [db] to depends_on: db: condition: service_healthy
  so the API container only starts after the DB is proven healthy.
- Add curl to the Dockerfile runtime stage so the healthcheck command
  is available in the final image.

Fixes #10
