fix(dashboard, js-sdk, types, medusa): separate between delete response with and without parent (#8852)

- Separate the previous `DeleteResponse` to `DeleteResponse` and `DeleteResponseWithParent`, as not every API route's delete response returns a parent. This ensures more accurate types shown in OAS / documentation.
- Use `DeleteResponse` or `DeleteResponseWithParent` in response API routes based on what they return
- Remove direct usage of `DeleteResponse` in API route, and instead create a type in the `type` package specific for the route / domain.
- Use the new types in the `js-sdk` and `dashboard`.
