feat(task-hierarchy): implement recursive task estimation and reset functionality

- Added SQL scripts to fix task hierarchy and reset parent task estimations to zero, ensuring accurate estimation calculations.
- Introduced a migration for a recursive task estimation function that aggregates estimations from subtasks, enhancing task management.
- Updated controllers to utilize recursive estimations for displaying task data, improving accuracy in task progress representation.
- Implemented a new API route to reset parent task estimations, allowing for better task management and data integrity.
