Implement route protection for onboarding

- Create ProtectedRoute component to guard routes based on onboarding status
- Protect all non-onboarding routes (dashboard, blog-writer, seo, etc.)
- Users must complete onboarding before accessing any features
- Prevents confusion and broken functionality for new users
- Improves user experience by guiding users through proper setup
