Feature: Add Scroll to Top Button

Currently, when users scroll down a long page, they need to manually scroll back up, which can be inconvenient.
To improve user experience and navigation, a Scroll to Top button can be added.

**🔹 Proposed Solution**

- Add a floating button (visible only when the user scrolls down).
- On clicking, it smoothly scrolls the page back to the top.
- Ensure the button is non-intrusive, responsive, and styled consistently with the website theme.

**✅ Benefits**

- Enhances accessibility and usability.
- Improves navigation for long pages.
- Provides a clean and modern UX touch.
