feat(translation): Post translation columns + settings + migration (#143 step 1)

Post gains post_title_translated / description_translated / translated_source_lang / translation_engine_version / translated_at — filled by the translate sweep so viewing is instant. ImportSettings gains translation_enabled (OFF by default), interpreter_base_url (EMPTY — no default host; the operator points it at their own Interpreter proxy behind a reverse proxy) and translation_target_lang (en), exposed + validated via /settings/import. Migration 0083. Settings defaults + patch + validation test.

+"""post-text translation via Interpreter (milestone 143) — Post columns + settings
+
+Post gains the translated title/description + the detected source language,
+Interpreter engine_version (cache key), and translated_at — filled by the
+translate sweep. ImportSettings gains translation_enabled (OFF by default),
+interpreter_base_url (EMPTY — the operator sets their own, behind a reverse
+proxy), and translation_target_lang (en).
