feat(task-management): enhance task grouping and localization support

- Implemented unmapped task grouping for better organization of tasks without valid phases.
- Updated task distribution logic to handle unmapped tasks and added a corresponding group in the response.
- Enhanced localization by adding translations for "noTasksInGroup" in multiple languages.
- Improved task list components to support custom columns and better task management features.
- Refactored task management slice to include loading states for columns and custom columns.
