fix(ci): restore proper Docker daemon gate on publish-workspace-server-image

main merged a fix (3206966e) that replaces the broken `Diagnose Docker
daemon access` step (|| true guards) with a proper `Verify Docker daemon
access` gate (docker info || { exit 1 }). The feature branch is still on
the old broken version — sync it.

mc#711: ubuntu-latest runners may lack a live Docker daemon. With the
old guards the step always succeeded even when Docker was inaccessible,
letting the build step hang for 4+ minutes before failing. The restored
gate fails in ~5s with an actionable error message.
