A status report with two sections both headed "network LAB" reads as one
network that is somehow working and empty at once. It was two networks:
the same name with different secrets, which is two different networks
that share nothing, because a network's identity is its name *and* its
secret.
Three fixes for the one confusion.
The heading now carries the network id, so the sections are plainly
different things. A name is a label the user chose; the id is the
identity.
Joining a name that is already configured with another secret says so, at
the moment it happens, because that is almost always a mistyped secret
and until now it silently produced an empty network sitting beside a
working one. `status` flags it too, for the case where it already
happened.
And the second network's emptiness now says why. It had no address
because the only configured range was already taken by the first — one
agent has one interface, so an address belongs to one network — and
"nobody else has joined" pointed at the wrong thing entirely. It now
names the range it cannot have, the reason, and the flag that gives it
one of its own.
Nothing was wrong with the connectivity: the working network's tunnel was
up and its ping was answering throughout.
