Scene: carry TagComponent lock/label on copy and duplicate

TagComponent is excluded from AllComponents/DuplicateComponents (its name
is copied specially at entity creation), so the editor-only Locked and
LabelColor fields were dropped by Scene::Copy and DuplicateEntity —
Ctrl+D on a locked or colour-labelled entity produced a bare duplicate.
Carry both fields explicitly in both paths, alongside the name copy.
