fix: address PR review comments for qwen-code provider

- Use qwenCodeOAuthPath option for custom OAuth credential paths
- Replace console.error with proper logger utility
- Use configured OAuth path when writing refreshed credentials
- Remove unnecessary non-null assertion on client property
- Remove unused apiKey and baseUrl from QwenCodeProvider type
- Add comprehensive tests for OAuth flow and error handling

Note: QWEN_OAUTH_CLIENT_ID left as-is per request
