ahp 0dcc7bbf76 ci: prebaked job image + fix buildx discovery under DOCKER_CONFIG ...

download.docker.com resets intermittently from the cluster network, and
/root/.docker/cli-plugins is not searched when the workflow sets
DOCKER_CONFIG=/tmp/.docker ('Docker buildx is required').

- jobs on the apollo runner use act-job:20 (.gitea/job-image: node 20 +
  docker CLI + buildx in system plugin paths) - no runtime downloads
- other runners fall back to installing, now into a system plugin path
