Theme toggle icon not fixed & inconsistent theme across pages

[Mrunalisa]

Summary: The theme toggle icon is not fixed on scroll and is missing or inconsistent across different pages, causing theme persistence issues.

Description:
While navigating through the NotesVault website, I observed the following issues:

1. Theme Toggle Icon Position Issue

   • The theme toggle icon is not fixed on scroll, causing it to move out of view.
   • This affects accessibility, as users cannot quickly switch themes when scrolling.

2. Inconsistent Theme Across Pages

   • Some pages display the default light theme, while others show the default dark theme.
   • On certain pages, the theme toggle icon is missing entirely.
   • Example: Pages with default white or default night theme have no toggle button.

Steps to Reproduce:

1. Open the NotesVault homepage.

2. Click on Student Account from the navigation bar.

3. Scroll down — observe that the theme toggle icon moves and disappears from view.

4. Navigate to other pages — notice that:

   • Some pages load with the default light theme.
   • Some pages load with the default dark theme.
   • Some pages have no theme toggle icon at all.

Expected Behavior:

• The theme toggle icon should remain fixed in position regardless of scroll.
• The selected theme should persist consistently across all pages.
• The theme icon should be present on every page.

Actual Behavior:

• Theme icon is not fixed.
• Theme changes are inconsistent across pages.
• Missing theme icon on some pages.

Evidence:
I have recorded a video demonstrating the issue.
