feat(enhanced-kanban): implement synchronous reordering for tasks and groups

- Added synchronous state updates for task and group reordering in the EnhancedKanbanBoard component, improving UI responsiveness during drag-and-drop operations.
- Introduced new actions `reorderTasks` and `reorderGroups` in the enhanced-kanban slice for better state management.
- Updated EnhancedKanbanGroup and EnhancedKanbanTaskCard components to utilize the new layout change animations, enhancing the user experience during reordering.
