test: GET /api/jobs/{id} should include workflow for running/pending jobs

Reproduces #14995: the jobs detail endpoint only embeds the workflow for
terminal (completed/failed/cancelled) jobs. Since the frontend caches
this response by job id and never refetches, a job opened while still
running or queued permanently loses its 'Open as workflow' / 'Add to
current workflow' actions, even after it finishes.
