fix : mise à jour in-app sans quitter l'application

- @capacitor/filesystem : téléchargement natif de l'APK (OkHttp)
- @capawesome-team/capacitor-file-opener : ouverture de l'installateur Android
- L'APK est écrit dans le cache de l'app puis ouvert via un Intent natif
- Plus de passage par le navigateur — tout se passe dans l'app
- file_paths.xml mis à jour pour couvrir le cache

package-lock.json
