Prevent my-traders API calls when user is not logged in

- Add authentication checks to SWR calls in App.tsx and AITradersPage.tsx
- Only call api.getTraders when user and token are available
- Modify loadConfigs to skip authenticated API calls when not logged in
- Load only public supported models/exchanges for unauthenticated users
- Update useEffect dependencies to include user and token
