Main navigation disappears after resizing to mobile
On mobile, resizing a desktop-loaded app page from 1440×900 to 390×844 removed the desktop sidebar without showing a replacement menu. On Agents, only the Overview/Credentials/Sessions selector remained, with no way to reach Projects, Settings, or the workspace menu. The same missing header persisted while navigating through project and environment pages. Reloading at the mobile size restored the Stashbase header and working “Toggle sidebar” button. I reproduced this again by loading Agents on desktop, resizing to mobile, and reloading. Update the navigation when the viewport changes rather than requiring a reload.
