[ENHANCEMENT] Add Dark/Light Theme Toggle to Help Center Page

[Eshajha19]

Summary

Added a Dark/Light theme toggle feature to the Help Center page to improve accessibility and user experience.

Changes Made

• Added a theme toggle button in the navbar
• Implemented JavaScript functionality to switch between light and dark themes
• Applied dark mode styles using the .dark-mode class
• Stored user theme preference using localStorage so the theme persists after page reload

Result

Users can now easily switch between light and dark modes on the Help Center page, and their preference will be remembered for future visits.
