Remove remaining mock data on catalog list item

What does this MR do and why?

This MR exchanges some fields in CiCatalogResource for the new structure.

You can view that structure from the backend perspective here.

The short version is that we are removing @client fields from the graphql query to instead use the newly added fields in the API.
