Rename containers/forgejo-runner to runner-job-image

The forgejo-runner container is the CI job execution environment (Dagger,
ArgoCD CLI, etc.), not the runner daemon itself. Rename to runner-job-image
to fix the version-check false positive (Dagger 0.19.11 vs daemon 12.7.0)
and clarify the distinction.

RUNNER_LABELS still references the old image name — will update after
building the image under the new name.
