Enhance onboarding flow with conditional routing

- Introduced OnboardingRoute component to conditionally navigate users based on onboarding status.
- Updated AppRoutes to utilize OnboardingRoute, redirecting users to the home page if onboarding is complete.
- Removed direct Telegram link from GetStartedStep to streamline onboarding process and improve user experience.

This update improves the onboarding experience by ensuring users are only shown the onboarding page when necessary.
