The honest "Docker cannot be used here" panel.

Rendered instead of an empty table whenever the probe in
containerization.views.docker_probe says the binary is missing or the daemon
cannot be reached.  It says which of the two it is, because the fixes are
different: install Docker, or give the root helper a 'docker' verb / start
dockerd.

          The panel runs unprivileged and reaches Docker through the root helper.
          Check that <span class="cpd-mono">dockerd</span> is running
          (<span class="cpd-mono">systemctl status docker</span>) and that the helper
          exposes a <span class="cpd-mono">docker</span> verb — until it does, every
