 * Column definitions for the default table-based list view.
 *
 * These are passed to the built-in `ListView` component and control which
 * fields appear as columns, their labels, sort behaviour, and formatters.
 *
 * Note: when a custom `listView` component is registered on the
 * `CollectionAdminConfig`, it receives the raw paginated data directly and
 * is responsible for its own layout. These column definitions can still
 * be used in a custom list view, but they are not automatically applied
 * as they are with the default table-based `ListView`. You can import
 * them if needed - for example if you wanted to create a toggled grid/table
 * custom view.
