* fix(reorder-columns): resolve incorrect column values order with detail-view enabled

Fixed an issue in the "reorder-columns" extension where columns had incorrect values when `data-detail-view` was set to true. The problem occurred because the code attempted to access a non-existent `field` property in the detail-view column. Added a check to ensure the `field` property exists before assigning the value.
