refactor(task-management): update search handling and improve task filtering

- Modified search handling to utilize the taskManagement slice for consistent state management across components.
- Enhanced placeholder text in search filters for better user guidance.
- Updated task fetching logic to ensure accurate search value retrieval from the correct state slice.
