Ruben Fiszel c8e4f31749 refactor(worker): drop docker image storage cap; scope rootless netns per-job
Remove the `docker_image_storage_size_mb` instance setting and the polling
storage monitor entirely. Now that `# docker` jobs are refused under nsjail
(the per-job podman daemon runs outside the sandbox), the asymmetry that
justified a docker-specific disk cap is gone: a normal job can already exhaust
host disk in non-nsjail modes, so a docker-only cap was inconsistent. Docker
jobs now use disk like any other job — bound it at the infra level.

Also scope the rootless slirp4netns network-backend override to the per-job
podman instance via a job-scoped `$HOME` containers.conf instead of a global
`/etc/containers` drop-in, so rootful podman elsewhere in the *-full image is
unaffected (flagged by cubic).

# Rootless container runtime (podman) for docker-mode jobs. When a `# docker` job
