fix(transaction): initialize CurrencyInput with a real currency code

vue-currency-input required a currency code for Intl.NumberFormat;
passing undefined threw inside the mount watcher, leaving the input
without listeners so amount stayed null on submit.

Use CurrencyDisplay.hidden to keep the symbol out of the field since
the currency selector is rendered separately.
