fix(direct-send): pass token balance to verified fiat calculator

The direct send flow was not passing the token balance to
verifiedFiatCalculator.compute(), so the calculator's balance
capping logic never fired. This caused submit intent failures
when a user tried to send back a small received amount in a
different currency (e.g. 0.01 CAD displayed as 0.01 USD when
the actual USD value was ~0.007).
