[FEATURE] Improved handling of unsaved changes

[ErHaWeb]

If the Close button is pressed in the TransFusion Connector, it is closed regardless of any changes. As an editor, you are used to being asked beforehand via a modal whether you really want to discard the changes.

I would also like to see this function for the TransFusion Connector. In particular, due to the editorial habit in other places that the close button does not immediately discard the change, a query should be made.

This will be a new feature in the "next level" coming in Q2 2024
