Define desired listener for the dynamic attribute category

[KremnevDmitry]

Environment

Jmix version: 2.3.999-SNAPSHOT

Bug Description

The following method was defined but does not work.

https://github.com/jmix-framework/jmix/blob/6e983d2ab989d41915beb85eb4b20a4104fde77d/jmix-dynattr/dynattr-flowui/src/main/java/io/jmix/dynattrflowui/view/category/CategoryDetailView.java#L408-L416

After support of declarative definition of SelectionListener (#3552) this syntax became possible, however the behavior of the method was not expected. It is necessary to fix the functionality.

The problem is not only cousing with not using designated method. The problem is with not setting orderNo field of "CategoryAttribute" entity.
