fix(infra): make postfix→batch bridge resilient and self-monitoring

Hardcoding the batch hostname in the mail-handler script meant a stale
image build (or COMPOSE_PROJECT_NAME change) could silently break
incoming mail for hours, with the only symptom being deferred queue
entries in the postfix log.

- freegle-mail-handler now reads the endpoint from BATCH_URL, set in
  docker-compose to use the service alias (batch-prod) which compose
  guarantees on the shared network regardless of container_name.
- Postfix healthcheck now also probes http://batch-prod:8080/up, so a
  broken bridge marks the container unhealthy rather than silently
  deferring mail.
