Improve PWA config for better browser support

Fixes #56

Update PWA configuration and service worker registration to improve robustness and compatibility with mobile web browsers.

* **Manifest Configuration:**
  - Add `"scope": "/"` to define the navigation scope.
  - Add `"description": "A text display app"`.
  - Add `"related_applications": []` to specify related applications.

* **Service Worker Registration:**
  - Update the service worker registration to use `/sw.js` instead of `/service-worker.js`.

* **InstallPWA Component:**
  - Add a check for `navigator.standalone` to detect if the app is already installed on iOS.
  - Add a check for `window.matchMedia('(display-mode: standalone)').matches` to detect if the app is already installed on Android.

* **WelcomeModal Component:**
  - Add a check for `navigator.standalone` to detect if the app is already installed on iOS.
  - Add a check for `window.matchMedia('(display-mode: standalone)').matches` to detect if the app is already installed on Android.

* **Workbox Configuration:**
  - Update the `swDest` to `dist/sw.js` instead of `dist/service-worker.js`.
