[FEATURE] add cypress tests for void payment in v2

### Feature Description

This implementation adds comprehensive V2 API testing for payment void/cancel operations across different payment states. The feature introduces a new Cypress test suite that validates three critical scenarios: successfully voiding a payment in the requires_capture state `after manual capture confirmation`, attempting to void a payment in the `requires_payment_method` state, and attempting to void a completed payment in the `succeeded` state.

### Possible Implementation

A new test file `VoidPayments.cy.js` contains three separate test contexts that verify void behavior across payment states using both manual and automatic capture flows.
