feat(frontend): allow Docker scripts on the multi-tenant cloud

Docker mode no longer relies on a privileged dind sidecar / host socket — each
# docker job runs in its own ephemeral rootless podman, torn down with the job,
with a per-job image-storage cap. So the hard block on app.windmill.dev is no
longer warranted. Remove the isCloudHosted() gate (+ now-unused imports) from the
script and flow inline-script pickers so Docker is selectable on cloud like any
other language. Requires the cloud worker fleet to run docker-capable workers
(*-full image + rootless podman) serving the auto-assigned 'docker' tag.
