feat: mobile UI overhaul — iPhone-style app grid, icon-only tab bar, fullscreen app sessions

- Add AppIconGrid: 4-column swipeable icon grid with page dots for My Apps on mobile
- Tab bar: remove text labels, square icon-only buttons (w-14 h-14), doubled padding
- Hide tab bar and top context tabs when app session is open
- App session header hidden on mobile, replaced with floating glass close button
- App sessions now render fullscreen on mobile without nav chrome
