Fix: Add Full Screen mode and update Tabs syntax

[amritamishra01]

This PR adds a responsive Full Screen mode to provide a distraction-free environment for users. It also updates the Tabs and Dropdown components to use the modern items and menu props to resolve console deprecation warnings.

steps:
Fullscreen Toggle: The page successfully enters a distraction-free fullscreen mode when you click the button, removing browser menus and the URL bar as requested.

State Management: The button correctly updates from "Fullscreen" to "Exit Fullscreen" once the mode is active, providing clear user feedback.

Responsive Layout: In the mobile view (around 0:20 in the video), the button intelligently collapses to show only the icon, preventing header clutter while maintaining the "Run" text.

Exit Modes: The application accurately handles exiting fullscreen through both the button click and the browser's native Esc key.

Closes #113

I tested this on Edge, Safari, and Brave browsers. It works like a charm. There are no console errors as well. Thank you so much for implementing this. Could you please remove the following code comments? I think they are not necessary.

Once these review comments are addressed, I think this would be good to merge!
