feat(dashboard,core-flows,js-sdk,types,link-modules,payment): ability to copy payment link (#8630)

what: 

- enables a button to create a payment link when a payment delta is present
- api to delete order payment collection
- adds a pending amount to payment collections

Note: Not the happiest with the decision on when to create a payment collection and when not to. The code should programatically create or delete payment collections currently to generate the right collection for the payment delta. Adding a more specific flow to create and manage a payment collection will help reduce this burden from the code path and onto CX/merchant.

Another issue I found is that the payment collection status doesn't get updated when payment is complete as it still gets stuck to "authorized" state
