Add search and sorting to dependency proxy manifest list
We need to add Search and Sorting to the dependency proxy manifest list backend GraphQL and frontend.
We will need:
- A dedicated finder/service that implements search and sorting
- Update the GraphQL API to accept search and sorting parameters
- Add the search and sorting UI to the frontend
The search functionality should search on the manifest name
Sorting should be by:
- Name
- Created At (cached)
- Version
Related to #250865 (closed).
