fix: improve Vertex AI authentication on Windows
- Add explicit ADC path detection for Windows and Unix systems - Automatically use ADC file when available instead of relying on environment variables - Add retry mechanism with gcloud CLI fallback for token refresh failures - Improve error handling for authentication failures in both streaming and completion methods - Add comprehensive tests for new authentication logic Fixes #8943
