DS Epic: Network Picker

### **Description**

A Network Picker component enables users to select and switch between different blockchain networks, displaying network names and statuses. It ensures smooth connectivity and interaction with various networks, enhancing user control and flexibility within the application.

The issue provides no files, tests, or entry points to begin from. First locate the design-system component structure and any existing network-related components, then clarify the picker’s required states, interactions, and supported networks. Done should be defined by an agreed component implementation and corresponding coverage, but the issue does not specify those criteria.
