Update how outgoing payments are created in card service

[mkurapov]

Currently, when we are initiating a transaction from cardService, we are calling the createOutgoingPaymentFromIncomingPayment mutation incorrectly, as we are passing in the incoming payment's incomingAmount as the debitAmount for the outgoing payment:

  variables: {
    walletAddressId,
    incomingPayment: payment.incomingPaymentUrl,
    debitAmount: {
      ...payment.incomingAmount,
      value: BigInt(payment.incomingAmount.value)
    },
    cardDetails: {
      signature: payment.signature,
      expiry: payment.card.expiry
    }
  }

This is incorrect because these amounts correspond to different wallet addresses, and could therefore be delineated in different assets.

Instead, we should update the createOutgoingPaymentFromIncomingPayment mutation to have debitAmount as optional. This will allow creating an outgoing payment (and under the hood, a quote) directly from the incomingAmount on the incoming payment.

Todo

• Update the createOutgoingPaymentFromIncomingPayment mutation to have debitAmount as optional
• Update how createOutgoingPaymentFromIncomingPayment mutation is called in cardService
