feat(ui): translation-forward post text + Settings card (#143 step 5)
PostCard + modal ProvenancePanel show the English title/description by default when
a translation exists, with a per-card "show original (<lang>)" toggle — translated
bodies render as plain text, originals keep their sanitized HTML. New
TranslationCard in Settings → Ingestion & filters: enable switch, Interpreter base
URL (generic placeholder, no default host), target language, a reachability
indicator + untranslated-posts count + "Translate now".
