Fix two bugs from remote: service name and IPv6 DNS ...

- Rename aegis-gateway back to aegis — envoy.yaml connects to hostname
  'aegis', renaming broke xDS entirely (Envoy got zero dynamic config)
- Add DNS Lookup Family V4_ONLY to tutorial cluster step — host.docker.internal
  resolves IPv6-first on Mac/Docker Desktop, causing connection failures
  to IPv4-only containers
