refactor: Remplacement de l'accès direct à Firestore par des Cloud Functions

Migration complète du backend pour utiliser des Cloud Functions comme couche API sécurisée, en remplacement des appels directs à Firestore depuis le client.

**Backend (Cloud Functions):**
- **Centralisation CORS :** Ajout d'un middleware `withCors` et d'une configuration `httpOptions` pour gérer uniformément les en-têtes CORS et les requêtes `OPTIONS` sur toutes les fonctions.
- **Nouvelles Fonctions de Lecture (GET) :**
    - `getEquipments`, `getContainers`, `getEvents`, `getUsers`, `getOptions`, `getEventTypes`, `getRoles`, `getMaintenances`, `getAlerts`.
    - Ces fonctions gèrent les permissions côté serveur, masquant les données sensibles (ex: prix des équipements) pour les utilisateurs non-autorisés.
    - `getEvents` retourne également une map des utilisateurs (`usersMap`) pour optimiser le chargement des données de la main d'œuvre.
- **Nouvelle Fonction de Recherche :**
    - `getContainersByEquipment` : Endpoint dédié pour trouver efficacement tous les containers qui contiennent un équipement spécifique.
- **Nouvelles Fonctions d'Écriture (CRUD) :**
    - Fonctions CRUD complètes pour `eventTypes` (`create`, `update`, `delete`), incluant la validation (unicité du nom, vérification des événements futurs avant suppression).
- **Mise à jour de Fonctions Existantes :**
    - Toutes les fonctions CRUD existantes (`create/update/deleteEquipment`, `create/update/deleteContainer`, etc.) sont wrappées avec le nouveau gestionnaire CORS.

**Frontend (Flutter):**
- **Introduction du `DataService` :** Nouveau service centralisant tous les appels aux Cloud Functions, servant d'intermédiaire entre l'UI/Providers et l'API.
- **Refactorisation des Providers :**
    - `EquipmentProvider`, `ContainerProvider`, `EventProvider`, `UsersProvider`, `MaintenanceProvider` et `AlertProvider` ont été refactorisés pour utiliser le `DataService` au lieu d'accéder directement à Firestore.
    - Les `Stream` Firestore sont remplacés par des chargements de données via des méthodes `Future` (`loadEquipments`, `loadEvents`, etc.).
- **Gestion des Relations Équipement-Container :**
    - Le modèle `EquipmentModel` ne stocke plus `parentBoxIds`.
    - La relation est maintenant gérée par le `ContainerModel` qui contient `equipmentIds`.
    - Le `ContainerEquipmentService` est introduit pour utiliser la nouvelle fonction `getContainersByEquipment`.
    - L'affichage des boîtes parentes (`EquipmentParentContainers`) et le formulaire d'équipement (`EquipmentFormPage`) ont été mis à jour pour refléter ce nouveau modèle de données, synchronisant les ajouts/suppressions d'équipements dans les containers.
- **Amélioration de l'UI :**
    - Nouveau widget `ParentBoxesSelector` pour une sélection améliorée et visuelle des boîtes parentes dans le formulaire d'équipement.
    - Refonte visuelle de `EquipmentParentContainers` pour une meilleure présentation.
