feat: optimisation du démarrage de l'application et de la gestion de l'authentification

- **Refonte du démarrage** : Mise en place d'un `AppInitializer` pour gérer l'initialisation asynchrone de Firebase et du cache en arrière-plan, réduisant le travail synchrone au lancement.
- **Sécurisation de l'authentification** :
    - Création d'un `AppStartGate` pour gérer proprement la restauration de la session Firebase Auth et les erreurs potentielles sur le Web.
    - Amélioration du `LocalUserProvider` avec un "bootstrap léger" permettant de rendre l'UID disponible immédiatement avant le chargement complet du profil.
    - Ajout de protections contre les erreurs d'accès à `FirebaseAuth.instance` (notamment pour les problèmes d'interop JS sur le Web).
- **Optimisation de l'UI** :
    - Remplacement du `AutoLoginWrapper` par une gestion plus robuste de la navigation post-authentification.
    - Amélioration de l'`AuthGuard` pour permettre l'affichage de certains écrans (comme le calendrier) pendant le chargement des données utilisateur (`allowWhileLoading`).
    - Ajout d'un écran de splash screen uniformisé (`StartupSplashScreen`).
- **Services & Cache** :
    - Introduction de `CacheService` utilisant `shared_preferences` pour le stockage local léger.
    - Refactoring des services (`AlertService`, `EmailService`, `FirebaseStorageManager`) pour accéder aux instances Firebase de manière plus flexible via des getters.
    - Mise à jour des dépendances dans `pubspec.yaml` pour inclure `shared_preferences`.
- **Calendrier** : Ajout d'une logique de chargement initial différé des événements (`_scheduleInitialEventsLoad`) pour éviter les appels redondants au démarrage.
- **Maintenance** : Mise à jour de la version de l'application à `1.1.23` et nettoyage des fichiers de cache de déploiement.
