[test_operator] Fix test_operator_results overwrite for multi-stage runs

When cifmw_test_operator_stages contains multiple stages of the same
type, the results dict key was just the framework name. Each stage
overwrote the previous result, so a failing middle stage was silently
masked if the final stage succeeded.

Include the stage name in the dict key so each stage gets its own
entry. The assert at the end of main.yml iterates dict2items, so it
checks all entries without further changes.
