Add Light Mode Toggle for Enhanced User Experience

[Umisalma848]

I would like to open a new issue to implement a light mode toggle feature. This enhancement will allow users to switch between dark and light themes based on their preference.

• Adding a light mode option will:
• Improve accessibility and readability in different lighting conditions
• Enhance overall user experience
• Provide a more personalized interface

Please let me know if I can work on this feature and submit a pull request.
