fix: show statusbar top border when sidebar is toggled

[schopr9]

Resolves #9118

Description

Fixes the statusbar top border visibility issue when toggling the organization sidebar.

Problem: When the organization sidebar is toggled, the statusbar's top border color disappears due to CSS Grid layout changes affecting the divide-x utility behavior.

Solution: Added conditional border-t styling to the statusbar

Changes Made

• Modified packages/insomnia/src/routes/organization.tsx to conditionally apply border-solid border-t border-[--hl-md] classes to the statusbar
• Used existing isOrganizationSidebarOpen state to control border visibility

Testing

• ✅ Linting passes
• ✅ TypeScript compilation passes
• ✅ Manual testing shows border appears/disappears correctly when toggling sidebar

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
