Make right sidebar responsive on small screens

[rishav-raj-genx]

This PR improves the responsiveness of the right sidebar (including the “What’s New” section and related panels) on smaller screens.

Problem

On tablet and mobile-sized screens, the right sidebar stays fixed in a way that can break the layout and reduce readability.

Screenshots

**Before (small-screens):

**After (small-screens):

Solution

• Added a responsive breakpoint at 1000px
• Stack the right sidebar below the main content
• Set the sidebar width to 100% on smaller screens
• Allow internal sidebar sections to wrap for better readability

Motivation

This improves the user experience on smaller devices without changing any existing functionality or behavior on desktop screens.

Testing:

• Tested locally using yarn watch
• Verified layout on desktop and small screen sizes using browser responsive mode

Notes

This is a small, UI-focused improvement aimed at improving mobile usability while keeping existing desktop behavior unchanged.

Hi maintainers,
The ci/circleci: api_sync check is failing with a Swagger/TypeScript generator error.
I did not modify any API or generated files in this PR (only CSS for responsiveness).
Happy to update/regenerate if needed, or let me know if this is a known CI issue.
Thanks!
