Wrong use statements for PHP 8.1 in Import class
Problem/Motivation
The class \Drupal\eca_ui\Form\Import uses proxy classes instead of the proper interfaces. This happened because of a copy&paste excercise for the config import code, that has a list of 10 injected dependencies.
The current usage is no problem for PHP 7.4 but it fails with PHP 8.1.
