events: drop wallet balance from the overview

The balance is still on Payments & payouts, which is where someone goes when they
actually care about it — the overview is for events, not billing.

Removes the BillingClient call behind it as well. Leaving that in place would have
kept an external billing API request on every overview load to render nothing,
and it was the controller's only use of the client, so the dependency goes too.
