Rename the screen and its ViewModel, UI state, and route to reflect that
they describe a MantraTranslationArtifactVersion:
- TranslationDetailScreen -> TranslationArtifactVersionDetailScreen
- TranslationDetailViewModel -> TranslationArtifactVersionDetailViewModel
- TranslationDetailUIState -> TranslationArtifactVersionDetailUIState
- TranslationDetailRoute -> TranslationArtifactVersionDetailRoute
Files moved with git mv to preserve history; all references (nav host,
artifact detail screen) updated.
