test: start the eng batching eval with its setup prerequisites supplied

Routing setup and cross-project learnings (D1/D2 in run 36385945043) are
never counted and are not what the case measures. The registration now uses
the runner's existing preconfiguredReviewActor so the attempt starts at the
review; engSetupAUQ still vetoes any late setup question. The registration
test pins the option.
