Translation cards in the artifact detail's Translations list are now
clickable, opening a translation detail screen.
- New TranslationDetailRoute + TranslationDetailScreen/ViewModel/UIState.
The screen shows the translation's details (name, dialect, visibility,
license, source version, author, created) and its chapters ordered by
index, each with translation progress (translated/total chunks, where a
chunk counts as translated once its text is non-empty).
- DAO queries getTranslationById, translation chapters by
translationArtifactVersionId, and translation chunks by
translationChapterId (validated by Room), exposed via MantraRepository
(impl + NO_OP).
- Extract the DetailRow composable (was private to ArtifactDetailScreen)
into a shared widgets/DetailRow.kt used by both detail screens.
