Fixed missing flex-col-reverse in desktop sidebar mode.
Issue:
- Desktop fullscreen (sidebar mode) was missing the flex wrapper
- PageHeader appeared above SubmenuBar instead of below
- Only mobile and wp-admin layouts had the fix
Fix:
- Added flex-col-reverse wrapper to desktop fullscreen layout
- Now all three layout modes have correct header ordering:
1. Desktop Fullscreen (Sidebar): SubmenuBar → PageHeader ✅
2. Mobile Fullscreen: PageHeader → SubmenuBar (mobile), SubmenuBar → PageHeader (desktop) ✅
3. Normal wp-admin: PageHeader → SubmenuBar (mobile), SubmenuBar → PageHeader (desktop) ✅
Result:
✅ Settings pages now show submenu tabs above contextual header
✅ Consistent across all layout modes
✅ Works on all screen sizes
