Final Class Crypto payment configuration — on-chain payment via a user-connected wallet or the Crossmint-hosted wallet flow. 
final class CrossmintCheckoutCryptoPayment
Set enabled to false to hide the crypto tab. When enabled, optionally attach a payer to let the app drive signing — CrossmintEvmWalletCheckoutPayer is the easiest way to bridge a CrossmintEvmWallet into a payer.
