AWS CI: Docker Checks for Test Email Failures

An AWS CI job can report green while the email step was never trustworthy. The Docker container is running, the application endpoint answers, and the test still cannot find its verification message. That is not a small test annoyance. It means the pipeline is missing a dependency signal.
