Subject: [PATCH] feat(backend/infra): add CI/CD pipeline with GitHub Actions

- Create .github/workflows/dotnet-ci.yml with:
  - Build and test job (runs on all pushes to main/feature branches)
  - Docker build job (builds and pushes to Docker Hub on main)
  - Deploy job (placeholder for production deployment)
- Configure workflow to run .NET 9.0 build, unit tests, and integration tests
- Update infrastructure-setup.md to mark CI/CD tasks as complete
- Feature 1.1 (Infrastructure Setup) now 100% complete
