Add additional fields to AccountingTransfers Admin API

[mkurapov]

Context

In the accountingTransfers Admin Query API, we can fetch all of the underlying accounting movements for a particular account. For example, for an outgoing payment, it would look something like this:

{
  "data": {
    "accountingTransfers": {
      "debits": [
        {
          "id": "8a6e9072-08d1-4495-887b-a1bc0bbccdc6",
          "debitAccountId": "92a92408-1bb2-4300-8b3c-ebb71d6c9032",
          "creditAccountId": "8d0f1efb-b763-4a17-883a-1d6f920202d9",
          "amount": "550",
          "transferType": "TRANSFER",
          "ledger": 1,
          "createdAt": "2024-11-19T14:09:15.664Z"
        },
        {
          "id": "3011637c-9799-4f32-98ce-a6a5f4cb1a85",
          "debitAccountId": "92a92408-1bb2-4300-8b3c-ebb71d6c9032",
          "creditAccountId": "8d0f1efb-b763-4a17-883a-1d6f920202d9",
          "amount": "550",
          "transferType": "TRANSFER",
          "ledger": 1,
          "createdAt": "2024-11-19T14:09:15.691Z"
        }
      ],
      "credits": [
        {
          "id": "e27878d7-03b3-466b-b6c1-a93b37b5020c",
          "debitAccountId": "00000000-0000-0000-0000-000000000001",
          "creditAccountId": "92a92408-1bb2-4300-8b3c-ebb71d6c9032",
          "amount": "668",
          "transferType": "DEPOSIT",
          "ledger": 1,
          "createdAt": "2024-11-19T14:09:15.426Z"
        }
      ]
    }
  }
}

where we funded the payment for 668, and made a transfer for 550. One of these transfers, however, is an expired, pending transfer that we made before we sent ILP packets to a separate Rafiki, but it isn't clear in the API. We should add state and expiresAt to the API result.

Todos

• Add state and expiresAt to the type AccountingTransfer in the Admin API schema
