// CheckAccountStatus retrieves the status of an account transaction based on the provided tracking ID.
//
// Parameters:
//   - trackingId: A unique identifier for the account.This should be obtained from a previous call to
//     CreateAccount or a similar function that returns an AccountResponse. The `trackingId` field in the
//     AccountResponse struct can be used here to check the account status.
//
//
// Returns:
//   - string: The status of the transaction as a string. If there is an error during the request or processing, this will be an empty string.
//   - error: An error if any occurred during the HTTP request, reading the response, or unmarshalling the JSON data.
//     If no error occurs, this will be nil.
