The two cards stop keeping numbers from each other

Charger control and Charger readings each held a reading the other did not.
Control's tiles showed the charger's operating state and the session's energy,
which appeared nowhere in the readout that claims to be the whole snapshot;
readings had the total power and the session length, which are the two numbers
you actually look at after pressing start to see whether anything happened.

Both gaps close. The control card grows two tiles — total power (20068) and
session length (20082) — laid out two by two beside the connector state and the
energy, and they use the readings card's own labels and formatting so the
wording cannot drift apart. They appear only when the charger reports them: the
OCPP status carries neither, so on that path the card keeps its original two
tiles rather than showing a pair of dashes.

The readings card grows the other two: the charging status (20097) leads the
live block, since what the charger is doing is what the block is about, and the
session energy (20084) follows the session length it belongs beside.

Nothing is exclusive to one card any more, which is the point — a number that
can only be read in the card that acts on it is a number you have to go looking
for.
