BIM+Draft: change object related version info to log messages

To inform the user warnings are shown if an object has new or modified properties in the current version. These warnings can however be confusing, especially if there are many. With this PR they are turned into log messages. They are also moved out of translation, and instead of the object Label the object Name is displayed.

Additionally:
Zero path length warnings for path arrays are now only displayed if the Align property is True.

See: #21180.
