fixup! test(node): Fix flaky postgresjs integration test

Use a docker-compose healthcheck + ready-gate sidecar so readiness is
gated on pg_isready succeeding inside the db container. The previous
match on 'database system is ready to accept connections' fired on the
initdb bootstrap postmaster and raced with its shutdown, causing
ECONNRESET on CI under load.
