[UX/UI] Sidebar responsiveness gap on intermediate screens (1280px) #1284

Hi OpenML Team,

While testing the portal, I noticed that the sidebar behavior is inconsistent on intermediate screen sizes like Nest Hub Max (1280px).

On mobile (iPhone SE), the sidebar correctly hides into a hamburger menu.

On 1280px, the sidebar remains fixed and takes up significant screen real estate.

Proposal: I suggest enabling the toggle/minify functionality for the 1280px resolution as well, so users can expand their workspace when needed.

I have intermediate skills in HTML, CSS, and JS and would like to work on this fix. Please assign this to me
