Type of Change

[x] New feature
[ ] Enhancement
[ ] Refactoring
[ ] Dependency updates
[ ] Documentation
[ ] CI/CD

Description

Added integrity check support for the GLOBEPAY connector to validate amount and currency consistency between request and response in the following flows:

Authorize – uses get_authorise_integrity_object()
PSync – uses get_sync_integrity_object()
Refund (Execute) – uses get_refund_integrity_object()
RSync – uses get_refund_integrity_object()

Changes Made

Added optional amount and currency fields to the GlobepayPaymentsResponse structure (Authorize flow).
Added optional amount and currency fields to the GlobepaySyncResponse structure (PSync flow).
Added optional refund_amount and currency fields to the GlobepayRefundResponse structure (Refund/RSync flows).
Implemented integrity checks in all handle_response functions for the above flows.
Each flow now extracts amount/currency from the response (with fallback to request data) and validates against the integrity object.

Motivation and Context

Closes #9180

Integrity checks ensure data consistency and security by validating that the amount and currency received from the connector match what was sent in the request. This prevents discrepancies in payment processing flows.

How did you test it?

Code follows the same integrity check pattern as in Xendit (#8049), Fiserv (#8075), Hipay (#9184), and Checkbook (#9160).
To test: hardcode mismatched amount or currency values in the connector request to trigger the integrity check failure.
