Bug: Crypto Amount Input Renders Prematurely

When the crypto selection is loading, the crypto amount input renders even if selectedCryptoCurrencyCode is undefined. This passes undefined to sprintf for the placeholder, causing malformed text (e.g., "Enter amount: undefined") to display instead of the "select wallet" button.

I see Cursor's point, but it shouldn't happen because selectedCrypto != null also implies selectedCryptoCurrencyCode != null, and so there's no case where this could happen.

If we want to be paranoid, we could put an extra || selectedCryptoCurrencyCode == null clause to make this explicit.
