FN-6065: fix pending-review advisory retry expectation

Adjust the reliability test to match the queued advisory retry path.

- update the plan-review UNAVAILABLE assertion to expect the task to requeue instead of fail
- assert the advisory path clears the error while incrementing the retry counter
- keep coverage that pending review should not record the executor review-pending failure
