Refactor ProcessSaleTransaction below Codacy line-limit

[Copilot]

Codacy flagged TransactionProcessorACLApplicationService.ProcessSaleTransaction for exceeding the 50-line limit. This change reduces the method footprint without changing the request/response flow or error handling behavior.

• Service refactor

  • Extracted sale-specific helper methods for:
    • access token retrieval
    • SaleTransactionRequest construction
    • request serialization into SerialisedMessage
    • success/error response mapping
  • Kept the orchestration in ProcessSaleTransaction focused on control flow.

• Behavior preserved

  • Sale request fields are still populated exactly as before, including:
    • transaction metadata
    • contract/product identifiers
    • operator and customer details
    • TransactionType = "SALE"
    • TransactionSource = 1
  • Response handling still returns the same mapped success payload and the same "0001" / "Process Sale Failed" error response on exceptions.

• Targeted regression coverage

  • Added a focused unit test that captures the serialized outbound sale request and asserts the expected payload and metadata are preserved after the refactor.

SaleTransactionRequest saleTransactionRequest = this.BuildSaleTransactionRequest(
    transactionNumber,
    deviceIdentifier,
    transactionDateTime,
    operatorId,
    customerEmailAddress,
    contractId,
    productId,
    additionalRequestMetadata);

SerialisedMessage requestSerialisedMessage =
    this.BuildSaleTransactionSerialisedMessage(estateId, merchantId, saleTransactionRequest);

@copilot tests are failing

I checked the failing PR run (23236758157) and the failure is in the integration-test login/setup step, not the ProcessSaleTransaction refactor: CI is failing with invalid_username_or_password for [email protected] during Run Integration Tests, while build and unit tests pass. I reran the full integration suite locally in Production and it passed on ea0a1b8, so I haven’t made a code change from this comment.
