feat: refactor service organization and update imports

- Introduced a new structure for services in `src/services/` to improve organization by domain, including core, analytics, data management, integrations, and task management.
- Moved relevant files to their new locations and updated all internal and external imports accordingly.
- Updated `TODO.md` to reflect the new service organization and outlined phases for further refactoring.

+```
+
+### Phase 1: Services Core (infrastructure) ✅
+- [x] **Déplacer `database.ts`** → `core/database.ts`
+  - [x] Corriger tous les imports internes des services
+  - [x] Corriger import dans scripts/reset-database.ts
+- [x] **Déplacer `system-info.ts`** → `core/system-info.ts`
+  - [x] Corriger imports dans actions/system
+  - [x] Corriger import dynamique de backup
+- [x] **Déplacer `user-preferences.ts`** → `core/user-preferences.ts`
+  - [x] Corriger 13 imports externes (actions, API routes, pages)
+  - [x] Corriger 3 imports internes entre services
+
+### Phase 2: Analytics & Métriques
+- [ ] **Déplacer `analytics.ts`** → `analytics/analytics.ts`
+  - [ ] Corriger imports dans hooks/components analytics
+- [ ] **Déplacer `metrics.ts`** → `analytics/metrics.ts`
+  - [ ] Corriger import dans `actions/metrics.ts`
+- [ ] **Déplacer `manager-summary.ts`** → `analytics/manager-summary.ts`
+  - [ ] Corriger imports dans components dashboard
+
+### Phase 3: Data Management
+- [ ] **Déplacer `backup.ts`** → `data-management/backup.ts`
+  - [ ] Corriger imports dans backup-scheduler et actions
+- [ ] **Déplacer `backup-scheduler.ts`** → `data-management/backup-scheduler.ts`
+  - [ ] Corriger imports dans API routes
+
+### Phase 4: Task Management
+- [ ] **Déplacer `tasks.ts`** → `task-management/tasks.ts`
+  - [ ] Corriger imports dans actions/tasks, hooks/useTasks
+- [ ] **Déplacer `tags.ts`** → `task-management/tags.ts`
+  - [ ] Corriger import dans `actions/tags.ts`
+- [ ] **Déplacer `daily.ts`** → `task-management/daily.ts`
+  - [ ] Corriger imports dans hooks/useDaily, actions/daily
+
+### Phase 5: Intégrations (déjà partiellement fait)
+- [ ] **Déplacer `tfs.ts`** → `integrations/tfs.ts`
+  - [ ] Corriger imports dans actions/tfs, API routes TFS, components TFS
+- [ ] **Déplacer services Jira** → `integrations/jira/`
+  - [ ] `jira.ts` → `integrations/jira/jira.ts`
+  - [ ] `jira-scheduler.ts` → `integrations/jira/scheduler.ts`
+  - [ ] `jira-analytics.ts` → `integrations/jira/analytics.ts`
+  - [ ] `jira-analytics-cache.ts` → `integrations/jira/analytics-cache.ts`
+  - [ ] `jira-advanced-filters.ts` → `integrations/jira/advanced-filters.ts`
+  - [ ] `jira-anomaly-detection.ts` → `integrations/jira/anomaly-detection.ts`
+  - [ ] Corriger tous les imports Jira dans actions, API routes, hooks
+
+### Points d'attention pour chaque service:
+1. **Identifier tous les imports du service** (grep)
+2. **Déplacer le fichier** vers le nouveau dossier
+3. **Corriger les imports externes** (actions, API, hooks, components)
+4. **Corriger les imports internes** entre services
+5. **Tester** que l'app fonctionne toujours
+6. **Commit** le déplacement d'un service à la fois
+
 ```
