Add GitHub Actions workflow for Docker container testing

- Created test-docker.yml workflow to build and test Ollama+voice agent container
- Tests Docker build, Ollama startup, model availability, and port accessibility
- Enables CI/CD testing without requiring local Docker setup
- Runs on pushes to main and voice-functionality-no-packages branches
