 * Mutation hook for deleting a shopping list.
 *
 * This hook provides automatic cache invalidation. When the mutation succeeds,
 * it invalidates the shopping-lists query to trigger a refetch of the updated list.
 *
 * @returns Mutation object with mutate function and state
 *
 * @example
 * ```tsx
 * const deleteShoppingList = useDeleteShoppingListMutation();
 *
 * const handleDelete = (listId: number) => {
 *   deleteShoppingList.mutate(
 *     { listId },
 *     {
 *       onSuccess: () => console.log('Deleted!'),
 *       onError: (error) => console.error(error),
 *     }
 *   );
 * };
