test: add tests for Qwen OAuth and fix config consistency

- Add qwen_oauth_test.go with 17 test cases for OAuth authentication
- Add qwen_provider_test.go with 15 test cases for Qwen provider
- Fix factory_provider.go to separate qwen and qwen-oauth protocols
- Add qwen API key and OAuth examples to config.example.json
- Export SetQwenTestEndpoints for testability

This addresses PR review feedback:
1. ✅ Add test files for CI automation
2. ✅ Fix configuration and documentation consistency
