fix(mobile): clean up action buttons, layout, and remove duplicate sidebar toggle

1. AppShell: Hide SidebarTrigger on mobile (md:hidden) to avoid duplicate with AppHeader's trigger
2. action-bar: Make maxVisible responsive - default 1 on mobile, 3 on desktop
3. DetailView: Hide share/edit/inline-edit buttons on mobile, add them to More menu
4. DetailSection: Use 2-column grid on mobile for better space utilization
