Register the firewall before assigning it

'no module of that name: firewall'. The networking family is computed by the
control plane, so the mesh knows those exist without anyone saying so; the
firewall is an ordinary catalogue module and has to be added like any other.

That is a second way for a module to be absent, and a less obvious one than
being present and placed nowhere — the mesh does not hold it at all, so nothing
can even report it unassigned.
