fix(ci-runner): connect component-tests job to the dind sidecar

The job container had no way to reach the docker-dind sidecar, so
'docker compose' failed with 'no such file or directory' on the unix
socket. Set DOCKER_HOST to the dind TCP endpoint and share the pod's
network namespace so the container can reach localhost:2375.
