Rename proximity anti-fraud check parameters

[banterCZ]

The payload for operation approval is not implemented correctly.

{
  "requestObject": {
    "id": "string",
    "data": "string",
    "proximityCheck": {
      "otp": "string",
      "type": "QR_CODE",
      "timestampRequested": "2023-07-18T07:56:49.516Z",
      "timestampSigned": "2023-07-18T07:56:49.516Z"
    }
  }
}

But should be

{
  "requestObject": {
    "id": "string",
    "data": "string",
    "proximityCheck": {
      "otp": "string",
      "type": "QR_CODE",
      "timestampReceived": "2023-07-18T07:56:49.516Z",
      "timestampSent": "2023-07-18T07:56:49.516Z"
    }
  }
}

Rename

• timestampRequested -> timestampReceived
• timestampSigned -> timestampSent
