Refactor USB drive list with dynamic selection and sorting

Updates the USB drive selection UI to align with other list views in the application. This change replaces the static "Select All" checkbox with a dynamic, selectable column that includes the checkbox in the header.

This refactoring provides a more consistent user experience and adds column sorting functionality to the USB drive list.

Additionally, the underlying shared function for creating selectable columns is improved to use the central UI state object for managing controls, removing the dependency on script-scoped variables for better encapsulation.
