fix: apply Docker 24 network workaround and smoke tests to production deploy

- Add SECRET_KEY env to deploy job for compose variable expansion
- Replace simple docker compose up with network stripping workaround
  (Docker 24 compose fails on external networks during container creation)
- Connect containers to networks manually after compose creates them
- Add smoke tests via docker exec against localhost:4000
- Create internal network manually when compose skips it
