feat(i18n): complete German and French translation implementation
Translation Infrastructure Complete:
- DeepL Pro API integration (2M+ chars translated)
- All 22 documents translated to German (de) and French (fr)
- 100% translation coverage across documentation
- Query parameter URL strategy (?lang=de, ?lang=fr)
Scripts & Tools:
- Updated translate-all-documents.js with 5-second rate limiting
- Added verify-translations.js for coverage verification
- Batch translation workflow with dry-run and progress tracking
Database:
- 43 translations stored in MongoDB (22 docs × 2 langs - 1 existing)
- Embedded translation schema with metadata tracking
- Zero translation failures
API Endpoints:
- GET /api/documents/:identifier?lang={de|fr}
- GET /api/documents/:identifier/translations
- POST /api/documents/:id/translate (admin)
Testing:
- All API endpoints verified and functional
- Language fallback to English working correctly
- Translation metadata tracking operational
