refactor(sort-orders): remove outdated deployment and implementation guides

- Deleted the `DEPLOYMENT_GUIDE_SORT_ORDERS.md` and `SEPARATE_SORT_ORDERS_IMPLEMENTATION.md` files as they are no longer relevant following the recent updates to the sort orders feature.
- Introduced new migration scripts to address duplicate sort orders and ensure data integrity across the updated task sorting system.
- Updated database schema to include new sort order columns and constraints for improved performance and organization.
- Enhanced backend functions and frontend components to support the new sorting logic and maintain user experience during task organization.
