🧪 test(dataform-service): add tests for runWorkflow and getCompilationResults

[max-ostapenko]

🎯 What: The testing gap addressed was missing tests for runWorkflow inside infra/dataform-service/src/dataform.js.
📊 Coverage: Covered both runWorkflow and getCompilationResults to ensure DataformClient wrapper correctly passes the requested configs and extracts responses.
✨ Result: Test coverage for dataform.js increased substantially by properly mocking Dataform APIs, reducing the risk of regressions on these core Dataform trigger functionalities.
