feat(enhanced-kanban): integrate ImprovedTaskFilters and fetchBoardSubTasks for enhanced task management

- Replaced the existing TaskListFilters with ImprovedTaskFilters in EnhancedKanbanBoard for better filtering capabilities.
- Updated EnhancedKanbanTaskCard to handle subtask expansion and fetching using the new fetchBoardSubTasks action.
- Added sectionId prop to EnhancedKanbanTaskCard and EnhancedKanbanGroup for improved task organization.
- Refactored project-view-header to utilize fetchEnhancedKanbanGroups for loading task groups.
