Fix CI Slack notifications never firing recovery alerts (#65119)
The artifact lookup for the previous notification state was using
'gh api' with -f parameters, which makes the CLI default to POST
instead of GET. The artifacts endpoint returns 404 on POST, so the
script always treated each run as the first one with no prior state.
That meant the 'all tests passing' recovery notification could never
fire, since it requires the previous state to contain failures.
Force --method GET on the artifact lookup and add unit tests covering
both the GET requirement and the determine_action state machine.
