feat: Intégration d'un assistant IA logisticien basé sur Gemini

Browse Source 
- Ajout d'une Cloud Function `aiEquipmentProposal` utilisant le modèle Gemini avec function calling pour suggérer du matériel et des containers.
- Implémentation de plusieurs outils (tools) côté serveur pour permettre à l'IA d'interagir avec Firestore : `search_equipment`, `check_availability_batch`, `get_past_events`, `search_event_reference` et `search_containers`.
- Ajout de la dépendance `@google/generative-ai` dans le backend.
- Création d'un service Flutter `AiEquipmentAssistantService` pour communiquer avec la nouvelle Cloud Function.
- Ajout d'une interface de dialogue `AiEquipmentAssistantDialog` permettant aux utilisateurs de discuter avec l'IA pour affiner les propositions de matériel.
- Intégration de l'assistant IA dans la section de gestion du matériel des événements (`EventAssignedEquipmentSection`).
- Mise à jour de `DataService` avec de nouvelles méthodes de recherche et de vérification de disponibilité optimisées pour l'assistant.
- Activation du mode développement et configuration des identifiants de test dans `env.dart`.
- Optimisation des paramètres de la Cloud Function (timeout de 300s et 1GiB de RAM) pour supporter les traitements IA.
