feat(dashboard,js-sdk,medusa): add ability to add outbound items to claim (#8502)

what:

- user can add/remove/update outbound items to a claim
- adds API to query variants

Note: There are several paths that are not implemented yet correctly, but have some code lying around. Those will be tackled in the followup PRs
