fix(chat): Correction race condition + Implémentation TODOs
## Corrections Critiques ### Race Condition - Statuts de Messages - Fix : Les icônes de statut (✓, ✓✓, ✓✓ bleu) ne s'affichaient pas - Cause : WebSocket delivery confirmations arrivaient avant messages locaux - Solution : Pattern Optimistic UI dans chat_bloc.dart - Création message temporaire immédiate - Ajout à la liste AVANT requête HTTP - Remplacement par message serveur à la réponse - Fichier : lib/presentation/state_management/chat_bloc.dart ## Implémentation TODOs (13/21) ### Social (social_header_widget.dart) - ✅ Copier lien du post dans presse-papiers - ✅ Partage natif via Share.share() - ✅ Dialogue de signalement avec 5 raisons ### Partage (share_post_dialog.dart) - ✅ Interface sélection d'amis avec checkboxes - ✅ Partage externe via Share API ### Média (media_upload_service.dart) - ✅ Parsing JSON réponse backend - ✅ Méthode deleteMedia() pour suppression - ✅ Génération miniature vidéo ### Posts (create_post_dialog.dart, edit_post_dialog.dart) - ✅ Extraction URL depuis uploads - ✅ Documentation chargement médias ### Chat (conversations_screen.dart) - ✅ Navigation vers notifications - ✅ ConversationSearchDelegate pour recherche ## Nouveaux Fichiers ### Configuration - build-prod.ps1 : Script build production avec dart-define - lib/core/constants/env_config.dart : Gestion environnements ### Documentation - TODOS_IMPLEMENTED.md : Documentation complète TODOs ## Améliorations ### Architecture - Refactoring injection de dépendances - Amélioration routing et navigation - Optimisation providers (UserProvider, FriendsProvider) ### UI/UX - Amélioration thème et couleurs - Optimisation animations - Meilleure gestion erreurs ### Services - Configuration API avec env_config - Amélioration datasources (events, users) - Optimisation modèles de données
