feat(task-management): add progress statistics and visual representation for task groups

- Implemented progress calculations for tasks grouped by priority and phase, including todo, doing, and done counts.
- Introduced a new GroupProgressBar component to visually represent task progress in the TaskGroupHeader.
- Updated TaskGroupHeader and TaskListV2Table to integrate progress data and display the progress bar conditionally based on grouping.
- Enhanced local storage handling for grouping preferences in the task management feature.
