test(auth): enhance auth integration tests with comprehensive coverage
- Restructure tests with better organization by functionality - Add comprehensive test coverage for all auth flows - Include OAuth authentication testing (registration and login) - Add password management tests (change password, reset password) - Test error scenarios and edge cases - Improve type safety with proper interfaces - Fix mock configuration and service interaction testing - Add tests for user registration, login, and verification flows
