Fix storing origin for workflow landing requests

The origin field was being accepted in the payload but not stored
to the model in create_workflow_landing_request(). This was
inconsistent with create_tool_landing_request() which correctly
stores the origin. Added a test to verify the origin is preserved
through create and claim operations.
