feat: complete Phase 5 of service refactoring

- Marked tasks in `TODO.md` as completed for moving TFS and Jira services to the `integrations` directory and correcting imports across the codebase.
- Updated imports in various action files, API routes, and components to reflect the new structure.
- Removed obsolete `jira-advanced-filters.ts`, `jira-analytics.ts`, `jira-analytics-cache.ts`, `jira-anomaly-detection.ts`, `jira-scheduler.ts`, `jira.ts`, and `tfs.ts` files to streamline the codebase.
- Added new tasks in `TODO.md` for future cleaning and organization of service imports.
