Replace k8s runner with ci-base image for local builds

- Remove forgejo-runner k8s manifests and ArgoCD app (runner now on indri)
- Remove build-runner workflow (no longer needed)
- Add ci-base image with Ubuntu 22.04 + common CI tools
- Add build-ci-base workflow to build the image
- Update test workflow to check docker instead of buildah
- Document bootstrap vs production mode for runner labels
- Configure host.docker.internal:5050 for zot access from job containers
