LPS-48299 Add new method to the SMDH interface to support to fetch existing model on the import site
LPS-48299 Add base implementation which tries to find the entity in the whole site hierarchy on the import side
LPS-48299 Add implementation to all the StagedGroupModel SMDH's
LPS-48299 We do not want to fail the import if the group doesn't present, instead we want to use the actual scopegroupd (and its parent groups) as a fallback
LPS-48299 We do not need these anymore since the base impl can handle the generic validation pattern
LPS-48299 Apply changes everywhere
LPS-48299 Fix failing tests
LPS-48299 Do not throw any exception for the fetcher method
LPS-48299 No need to throw exception here anymore
LPS-48299 This message is not true now
LPS-48299 Special layout behavior requires special treatment, mirroring the same logic we have in the BaseSMDH temporarily
LPS-48299 Missing refactor for PollsVote
LPS-48299 No need to throw exception here - this method should return with a true or false and that's it
