Fixes #2276.

Doesn't that this keep the combobox enabled in the DAO mode when at payment screen? Maybe it requires an if check ro the dao mode?

[ripcurlx]

If the DAO is activated there is the additional step where you select the trade fee currency (BTC or BSQ), so there is no need to be able to switch the payment account also in the show funds screen. Before the DAO, you switch directly to the Pay Funds screen if there is no range to choose from, so it wouldn't be possible to switch to another payment account. That's why I needed to add this check.

if (DevEnv.isDaoActivated()) {
            paymentAccountsComboBox.setMouseTransparent(true);
            paymentAccountsComboBox.setDisable(true);
            paymentAccountsComboBox.setFocusTraversable(false);
}
