Subject: [PATCH] fix: Improve numbering rule handling and item routing
 functionality

- Added temporary debug response in `numberingRuleController` for better troubleshooting.
- Refactored SQL queries in `NumberingRuleService` to enhance parameter handling and improve clarity.
- Updated `ItemInfoPage` to correctly handle manual input values for user-generated codes.
- Implemented sorting logic in `ItemRoutingTab` to prioritize default routing versions and added functionality to set a version as default.

These changes aim to enhance the reliability and user experience in managing numbering rules and item routing processes.
