feat: enhance AchievementCard and ManagerSummaryService logic

- Added logic to differentiate between regular achievements and todos in `AchievementCard`, changing background color accordingly.
- Updated todos count display to only show for non-todo achievements, improving clarity.
- Refactored `ManagerSummaryService` to remove outdated filters and allow unlimited display of accomplishments and challenges, enhancing data visibility.
- Simplified priority handling by including 'urgent' as a high priority, ensuring better task categorization.
