feat(connector): [Chargebee] Add Integrity Check Support for Authorize, PSync, Refund and RSync Flows

[nabeel001]

Type of Change

• Bugfix
• New feature
• Enhancement
• Refactoring
• Dependency updates
• Documentation
• CI/CD

Description

• Add amount and currency_code fields to ChargebeePaymentsResponse struct
• Add amount and currency_code fields to RefundResponse struct
• Implement integrity checks in handle_response methods for:
  • Authorize flow using get_authorise_integrity_object
  • PSync flow using get_sync_integrity_object
  • Refund flow using get_refund_integrity_object
  • RSync flow using get_refund_integrity_object
• Set integrity_object in router_data.request for all flows
• Follow same pattern as other connectors (XENDIT, FISERV)

This ensures data consistency and correctness when dealing with amounts
between Hyperswitch and Chargebee connector, preventing discrepancies
in payment processing flows.

Fixes #9159
