feat(task-management): add all_labels support and improve label handling

- Introduced all_labels property in task management to provide a complete list of labels for selection logic.
- Updated TasksControllerV2, TaskRow, and LabelsSelector components to utilize all_labels for enhanced label management.
- Improved checkbox handling in LabelsSelector to prevent event propagation and ensure better user interaction.
- Enhanced useTaskSocketHandlers to manage temporary subtasks effectively, preventing duplication during optimistic updates.
