Implement comprehensive redirect logic in the Root Layout that:
- Redirects unauthenticated users to login screen
- Checks if authenticated users need to complete onboarding (firstName)
- Prevents redirect loops by only redirecting on initial mount
- Protects tabs from unauthorized access (redirects to login on logout)
- Lets auth screens handle their own navigation via NavigationController
Add comprehensive test suite with 8 tests covering:
- Initial redirect scenarios (authenticated/unauthenticated)
- Onboarding flow (missing firstName)
- Logout protection
- Loading states
Update jest.config.js to support expo-status-bar, expo-splash-screen,
react-native-reanimated, and react-native-worklets transforms.
