test: add comprehensive test suite with 89% coverage
- Add tests for all backend modules: config, database, models, services, routes, middleware, and providers - Separate dev dependencies using dependency-groups - Update CLAUDE.md with test commands and project structure - Add .coverage and .pytest_cache to gitignore 88 tests covering: - Authentication and authorization - Model routing and key selection - Async logging with batch processing - All API endpoints (chat, openai, anthropic, health) - LiteLLM wrapper (mocked external calls) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
