Fix/mobile menu resize bug

[pari-dubey1]

Summary [required]

This PR fixes a responsive navigation issue where the mobile hamburger menu remained open when resizing the browser window from mobile view to desktop view. This caused both the mobile and desktop navigation menus to appear simultaneously.

The fix adds a resize listener that automatically closes and resets the mobile navigation state once the viewport crosses the desktop breakpoint, ensuring consistent responsive behaviour across screen sizes.

Additionally, while testing and debugging the issue, several unintended JavaScript syntax and duplicated logic issues in script.js were identified and cleaned up to restore proper functionality of the navbar and overall client-side interactions.

Notes for Reviewer

While implementing the responsive navbar fix, some pre-existing duplicated JavaScript blocks and syntax inconsistencies in script.js were discovered that prevented the navbar interactions from functioning correctly. These were cleaned up to restore stable client-side behaviour and ensure accurate testing of the assigned issue.
