💫 UI Enhancement: Added AOS Scroll Animations + Fixed Auth Page Crash

[Code-master-pragyan]

📄 Description

This PR introduces UI enhancement with smooth scroll animations using AOS (Animate On Scroll).
Additionally, while setting up the project locally, I fixed minor crashes in signin.js and signup.js caused by unwanted else blocks. No authentication logic was modified — only the error was removed to ensure smooth local development.

✅ Checklist

• My code follows the project’s coding guidelines.
• I have tested these changes locally.
• I have added necessary documentation/comments (if applicable).
• I have linked the related issue (if applicable).

🙏 Additional Notes

• AOS is lightweight and well-maintained, ensuring no crashes or conflicts with the existing project.
• These changes improve user experience and visual appeal without affecting the core logic.
