address lint+pyre failures

Summary:
OSS linter seems to be failing (https://github.com/facebook/Ax/actions/runs/8142510522/job/22252224158). This addresses the observed failures.

May be related to https://fb.workplace.com/groups/aeeng/permalink/1603431750415515/

Also moves some pyre-ignores that were out of place, per failing pyre command.
