Fix async test: wait for metrics service (port 8070) before running tests

The second E2E suite tests http://localhost:8070/v1/metrics but the
Makefile only waited for keycloak (8080) and registry (8081). Metrics
starts after both kafka and registry are healthy, so it may not be
ready by the time Karate reaches that test. Add wait_for_port.sh 8070
to ensure the metrics service is accepting connections first.
