feat: Mise à jour à la version 1.1.20 et amélioration de la recherche d'équipements

- Mise à jour de la version de l'application à `1.1.20` dans `app_version.dart`, `version.json` et `CHANGELOG.md`.
- Optimisation de la fonction Cloud `getEquipmentsPaginated` pour supporter la recherche par ID exact (document ID ou ID legacy) et améliorer la recherche textuelle avec filtrage par lots.
- Amélioration de la gestion des alertes dans `processEquipmentValidation.js` :
    - Ajout d'un statut `NOT_TAKEN` pour éviter les fausses alertes d'équipements perdus s'ils n'ont jamais été emportés.
    - Refonte complète du parsing des dates Firestore pour une meilleure robustesse dans les alertes.
    - Correction de la validation des quantités (vérification du type `number`).
- Ajout de méthodes statiques dans `EventPreparationService` (`shouldMarkEquipmentAsLost`, `isEquipmentNotTakenToEvent`) pour centraliser la logique de détermination du statut des équipements au retour.
- Mise à jour de `EventPreparationPage` pour intégrer le nouveau statut `NOT_TAKEN` et utiliser la logique centralisée du service de préparation.
- Mise à jour des fichiers de cache Firebase Hosting.
