feat: add nostrclient status indicator and connection button

- Add /api/v1/status endpoint to check nostrclient availability
- Add color-coded "Connect" button (red/orange/green) based on status
- Show dropdown with connection details (relays count, websocket status)
- Add warning banner when nostrclient extension is not available
- Update info card with description of extension functionality

Closes #132
