Use docker compose --wait for Kafka startup

Replace the custom bash readiness loop with `docker compose ... up -d --wait` in CI and PR workflows. This simplifies startup of the microservices-messaging Kafka service and removes the manual retry/polling logic. Files changed: .github/workflows/maven-ci.yml, .github/workflows/maven-pr-builder.yml. Note: requires a Docker Compose version that supports the `--wait` flag.
