HistoryDatasetCollectionAssociation.copy() was internally calling copy_tags_from(), but both callers (History.copy() and DatasetCollectionManager.copy()) also called copy_tags_from() on the returned HDCA, resulting in every tag being duplicated. Move the tag-copying responsibility entirely into HDCA.copy() via a new target_user parameter (falling back to source history user), and remove the redundant copy_tags_from() calls from both callers. This is safer than the reverse approach since any future caller of HDCA.copy() will get correct tag copying automatically. Fixes galaxyproject#21872

`__datasets_for_update` can return an empty list when the given ID doesn't match an HDA in the history, causing an unhandled IndexError.
The test was using the legacy untyped endpoint which defaults to dataset type, causing a 500 error when updating a collection's tags.
