feat(database): optimize task sorting functions and introduce bulk update capability

- Added new SQL migration to fix window function errors in task sorting functions, replacing CTEs with direct updates for better performance.
- Introduced a bulk update function for task sort orders, allowing multiple updates in a single call to improve efficiency.
- Updated socket command to support bulk updates, enhancing the task sorting experience in the frontend.
- Simplified task update handling in the frontend to utilize the new bulk update feature, improving overall performance and user experience.
