Default missing review_rejected to False

[sihrc]

Summary

• default WorkflowResult.review_rejected to False when key is missing
• add a targeted regression test for that property behavior

Why

The observed runtime error is from strict access in workflow_object.py when payloads omit review_rejected.

Testing

• Added test:
  • tests/types/test_worflow_result.py
• Local execution note: unable to run pytest in this environment due to missing indico dependency (ModuleNotFoundError: No module named 'indico').

---

Note

Low Risk
Small defensive change to result parsing plus a unit test; minimal behavioral impact beyond avoiding errors on missing fields.

Overview
WorkflowResult.review_rejected now defaults to False when review_rejected is missing from the result payload instead of raising on strict key access.

Adds a regression test ensuring omitted review_rejected is treated as not rejected.
