[Feature] UI - Models Page: Model Search

[yuneng-jiang]

Relevant issues

This PR implements the Model Search in the backend endpoint /v2/model/info. Previously this endpoint was not paginated and returns the entire list, so client side filtering worked. Now the list is paginated, and the endpoint needs to search the backend instead.
