fix: fix CI test failures for postgres and elasticsearch

- Normalize RefreshedAt in test assertion helpers to avoid timestamp
  mismatch after insert/update now sets refreshed_at
- Move ES_TEST_SERVER_URL env var from service container to job level
  so the runner process can discover the ES instance
