## **Description**
This PR introduces the UI implementation for the Multi-RPC Modal, which
is part of the broader initiative to support multiple RPC endpoints for
networks. The modal allows users to view and select from multiple RPC
options for a specific network, ensuring a smoother transition or switch
between different endpoints.

**UI Only: This PR focuses solely on the implementation of the UI. The
modal is not yet integrated or functional in the application as it
requires the upgrade of the Network Controller to version v21.**
