[Feature] : Add Scroll To Top Button across all pages.

[rajgharat07]

Description :

Implement a "Scroll to Top" button that appears when users scroll down the page. The button should be positioned in the lower right corner of the screen and smoothly scroll the user back to the top of the page when clicked. The feature should be present on all pages for better navigation and user experience.

Requirements:

• Button appears after the user scrolls a certain distance (e.g., 300px down the page).
• Button should have a subtle animation when it appears and disappears.
• The scrolling behavior should be smooth when returning to the top.
