feat: Enhance category column handling and data mapping

- Updated the `getCategoryColumnsByCompany` and `getCategoryColumnsByMenu` functions to exclude reference columns from category column queries, improving data integrity.
- Modified the `TableManagementService` to include `category_ref` in the column management logic, ensuring proper handling of category references during data operations.
- Enhanced the frontend components to support category reference mapping, allowing for better data representation and user interaction.
- Implemented category label conversion in various components to improve the display of category data, ensuring a seamless user experience.
