feat(app-bar): detect standalone mode and adjust padding

- Added `isRunningStandalone` utility in `src/utils/front.ts` to detect if the app is running as a standalone PWA or in a native container (iOS Safari, Android Chrome, etc.).
- Updated `AppBar.tsx` to conditionally apply bottom padding only when running in standalone mode, ensuring better layout alignment within custom containers.
