fix: apply tokenBalanceTextProps only to TokenBalanceView, not FiatBalanceView

When inlining the balance text style logic, tokenBalanceTextProps overrides
were incorrectly applied to FiatBalanceView instances too. Only TokenBalanceView
should receive the caller-supplied text overrides (variant/color/style); fiat
balance views must always use the plain base constants.
