fix(mobile): resolve Android status-bar overlap via safe-area plugin

Android WebView returns 0 for env(safe-area-inset-top) by default, so the
CSS-only header inset had no effect on edge-to-edge devices (API 35+).

- Add @capacitor-community/safe-area@^7.0.0 (Capacitor 7 compatible); it
  patches the webview so env(safe-area-inset-*) report real values. Enabled
  natively (no JS init), so it works in remote/live mode too.
- capacitor.config.ts: declare SafeArea plugin (initialViewportFitCover).
- mobile-run-android.sh: idempotently enable EdgeToEdge in MainActivity after
  cap add (android/ is generated/gitignored), required by the plugin.
