fix: Bug - Android app view is below titlebar and action bar on android

Respect Android system bar insets with safe-area shell padding, inset-aware modal and bottom-sheet layouts, transparent edge-to-edge themes, and a Capacitor SystemBars refresh on mobile startup.

 ## Safe area (Android)
 
-- Capacitor `SystemBars` injects `--safe-area-inset-*` CSS variables into `document.documentElement`. `index.html` sets `viewport-fit=cover` and default inset values; `main.ts` calls `applyMobileSafeAreaDefaults()` so injection never hits a missing root element after the WebView loads.
+- Capacitor `SystemBars` injects `--safe-area-inset-*` CSS variables into `document.documentElement`. `index.html` sets `viewport-fit=cover` and default inset values; `main.ts` calls `applyMobileSafeAreaDefaults()` so injection never hits a missing root element after the WebView loads. `MobileAppLifecycleService` calls `syncMobileSafeAreaInsets()` after Capacitor boot so Android SystemBars recomputes inset variables once the SPA is ready.
 - `capacitor.config.ts` sets `plugins.SystemBars.insetsHandling: 'css'` so Android WebView versions that mis-report `env(safe-area-inset-*)` still receive correct insets.
-- Global `styles.scss` applies inset padding on `html` (with `env()` fallback) and sizes `app-root` to `height: 100%` so content stays below the status bar and above the navigation bar in edge-to-edge mode.
+- Global `styles.scss` defines `metoyou-safe-area-shell` (mobile app shell padding), `metoyou-fixed-safe-viewport` (full-screen modals/backdrops), and `metoyou-fixed-safe-bottom-sheet` (bottom sheets and CDK profile-card panels). These read `--safe-area-inset-*` with `env()` fallback so routed pages, settings, context menus, and profile cards stay below the status bar and above the navigation bar.
+- Android `styles.xml` uses transparent status/navigation bars and `windowLayoutInDisplayCutoutMode=shortEdges` so Capacitor can draw edge-to-edge and report accurate insets.
