fix(core-flows): Allow create shipping methods through order edits

[JohnGemstone]

Fixes for #11559 and #11558

Noticed there's a recent pull request #11504 which fixes what's passed to prepare-shipping-method.

As for updating the query for CreateOrderEditShippingMethodWorkflowInput entry point from order_claim to orders, it seems like this has already been fixed??

For my own education, how can github say I'm two commits ahead from the main develop branch but show what I'm merging into is different from the codebase...
See:
9fb265c

I can't even seem to find when this line was changed:
/packages/core/core-flows/src/order/workflows/order-edit/create-order-edit-shipping-method.ts#L118

What has happened?
