feat: Add Numbering Rule APIs and Frontend Integration

- Implemented a new API endpoint to retrieve numbering rules based on table and column names, enhancing the flexibility of numbering rule management.
- Added a new service method to handle the retrieval of numbering columns specific to a company, ensuring proper company code filtering.
- Updated the frontend to load and display numbering columns, allowing users to select and manage numbering rules effectively.
- Refactored existing logic to improve the handling of numbering rules, including fallback mechanisms for legacy data.

These changes enhance the functionality and user experience in managing numbering rules within the application.
