Sorting by Wikibase Type malfunctioned in testing the migration of the scraper to Postgres; we need to identify the issue and resolve it.

AC:

• Backend can return the paginated list of wikibases sorted by wikibase type - check with product what sort order is preferable, as sorting by enum and sorting by frontend label will be different
• Sorting by type re-enabled on frontend - affected areas marked by TODO comments, inc frontend tests
• Backend tests are de-skipped and pass muster
