fix(tests): Correct test assertions for CI/CD environment

- test_termination_on_timeout: Accept "timeout_synthesis_failed" reason
since unit tests run without API keys, causing synthesis to fail

- test_graph_execution_flow: Mock get_model() to return "test" provider
since pydantic-ai needs a valid model string during Agent init

Both fixes address test failures in environments without LLM API keys.
