Restore check-status response parity for polling and failed orchestrations #232

Summary

Bring create_check_status_response() and wait_for_completion_or_create_check_status_response() into parity with the Durable Functions HTTP management API.

This groups the closely related response-status, polling-header, and status-query URL behavior into one focused change.

Current behavior

• create_check_status_response() omits the standard Retry-After: 10 header that both the v1 Python SDK and the Durable Functions host emit for the asynchronous HTTP pattern.
• wait_for_completion_or_create_check_status_response() returns HTTP 500 unconditionally for failed orchestrations.
• Callers cannot opt into returnInternalServerErrorOnFailure when creating a check-status response or management payload.

The Durable Functions host defaults failed status queries to HTTP 200 and returns HTTP 500 only when returnInternalServerErrorOnFailure=true is requested. See Azure/azure-functions-durable-python#314.

Expected behavior

Add a Python-style return_internal_server_error_on_failure: bool = False option and apply it consistently across:

• async create_check_status_response();
• sync create_check_status_response();
• create_http_management_payload();
• wait_for_completion_or_create_check_status_response().

When enabled, statusQueryGetUri must include returnInternalServerErrorOnFailure=true. The wait helper must return HTTP 200 for a failed orchestration by default and HTTP 500 only when the option is enabled. Timeout responses must preserve the option in their status-query URL.

Acceptance criteria

• Check-status responses include Location, Content-Type: application/json, and Retry-After: 10.
• Failed orchestrations return HTTP 200 by default from the wait helper.
• Failed orchestrations return HTTP 500 when return_internal_server_error_on_failure=True.
• Generated statusQueryGetUri includes the host query parameter only when enabled.
• Async and sync clients have matching behavior.
• Unit tests cover initial responses, timeout responses, and completed/terminated/failed terminal states.
