14. Translation Pipeline

Multilingualism works via separate translation per page:

1. User triggers POST /api/projects/:id/pages/:pageId/translate { targetLanguages: ['en', 'fr'] }
2. Service iterates over languages
3. Per language: chatComplete(MODEL_TRANSLATOR, systemPrompt, mdContent) — Default google/gemini-2.5-flash
4. Result is written to pageTranslations with Hash + translatedAt
5. On re-translate: if mdHash unchanged → Skip
6. Manual-Edit-Flag prevents overwrite
