[NAVREDESIGN] Network Switcher Component

### **Description**

Create `Network Switcher` component for opening `NetworkSwitcher` screen

### **Technical Details**

- This component is essentially a button
- Consumes data from redux with network information
- Color and icon may be hardcoded and referenced from the app level
- Renders icon, label, and colors based on whatever network is selected

### **Acceptance Criteria**

- TBD

### **References**

- Figma - https://www.figma.com/file/qcwJHEEw5qyNru5mbFf6Oq/Nav-Redesign-Breakdown?node-id=101%3A618
- ETA - 2 Days

Start with the NetworkSwitcher screen and the Figma reference, then inspect how Redux exposes the selected network and how nearby navigation buttons are structured. Done means a button component renders the selected network's icon, label, and color and opens NetworkSwitcher; acceptance criteria still need clarification.
