fix: use consistent ORDER_INCREMENT value for task ordering

- Fixed bug where TasksTab used 100 while utils used 1000 for increments
- Exported ORDER_INCREMENT constant from task-ordering utils
- Updated TasksTab to import and use the shared constant
- Ensures consistent task ordering behavior across the application
