Description

The current Light Mode icon used in the UI looks similar to a settings gear instead of a sun or light indicator. This causes confusion because users may think the icon opens settings rather than toggling the theme.

To Reproduce

Steps to reproduce the behavior:
Go to any page in the application.
Locate the theme toggle button (top-right of the navbar).
Observe the Light Mode icon (gear-like sun shape).
See that it resembles a settings/gear icon instead of a light mode indicator.

Expected behavior

The Light Mode icon should clearly indicate theme switching, not settings.
A correct icon should look like a sun, light bulb, or recognizable light theme symbol.
