Setting up the connection is not the same as using it

The control card opened with the parts that get touched once — which charger,
and where it lives on the network — and only then reached what gets used every
day. Split in two: a connection card holding the picker, the address and the
connected badge, then a control card holding the tiles and the buttons.

The not-connected hint and the error line move up with the connection, since
that is what they are about, and the control card simply does not appear until
there is a connection to control over. That also retires the inner template
that repeated the card's own condition.
