fix: iOS PWA status bar overlap issue on mobile devices

- Add PWA detection logic to App.jsx
- Apply dynamic padding to header and sidebar in PWA mode
- Update viewport meta tag for better iOS compatibility
- Change status bar style to black-translucent for PWA
- Add CSS variables for safe area insets with fallback support

This ensures menu button and sidebar content are properly visible
below the iOS status bar when installed as a PWA.
