feat: production deployment - full update with providers, admin, glossaries, pricing, tests
Major changes across backend, frontend, infrastructure: - Provider system with model selection (Google, DeepL, OpenAI, Ollama, Google Cloud) - Admin panel: user management, pricing, settings - Glossary system with CSV import/export - Subscription and tier quota management - Security hardening (rate limiting, API key auth, path traversal fixes) - Docker compose for dev, prod, and IONOS deployment - Alembic migrations for new tables - Frontend: dashboard, pricing page, landing page, i18n (en/fr) - Test suite and verification scripts Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
