feat: complete Phase 4 of service refactoring

- Marked tasks in `TODO.md` as completed for moving task-related files to the `task-management` directory and correcting imports across the codebase.
- Updated imports in `seed-data.ts`, `seed-tags.ts`, API routes, and various components to reflect the new structure.
- Removed obsolete `daily.ts`, `tags.ts`, and `tasks.ts` files to streamline the codebase.
- Added new tasks in `TODO.md` for future cleaning and organization of service imports.
