[Woo POS][Non-Simple Products] Redirect to Items screen after cash payment

[AnirudhBhat]

Closes: #13255

Description

This PR updates the navigation logic to ensure that, after a successful payment (via card or cash), users are redirected internally to the Items List screen. This guarantees that when users click on the "New Order" button on the success screen, they are returned directly to the Items List screen, bypassing any intermediate screens like the Variations screen visited during the previous checkout flow.

Steps to reproduce

Card payment

1. Navigate to POS (More menu -> POS)
2. Click any Variable product
3. Select any variation and proceed for checkout
4. Complete the payment using card and click on "New Order" button on payment success screen
5. Ensure you are taken back to items list screen

Cash payment

1. Navigate to POS (More menu -> POS)
2. Click any Variable product
3. Select any variation and proceed for checkout
4. Complete the payment using cash and click on "New Order" button on payment success screen
5. Ensure you are taken back to items list screen

Thank, LGTM!

Good idea to move this logic here, instead of duplicating it for card and cash payments on the calling site!
