refactor: enhance task completion ratio calculation and reporting

- Updated the `get_task_complete_ratio` function to improve handling of manual, weighted, and time-based progress calculations.
- Added logic to ensure accurate task completion ratios, including checks for subtasks and project settings.
- Enhanced error logging in the `refreshProjectTaskProgressValues` method for better debugging.
- Introduced new fields in the reporting allocation controller to calculate and display total working hours and utilization metrics for team members.
- Updated the frontend time sheet component to display utilization and over/under utilized hours in tooltips for better user insights.
