Cleanup now runs its IAM/multipart steps only when setup reached them, so
an early setup failure still removes the bucket. Added a DELETE

A failed setup previously skipped cleanup, leaking the bucket and IAM

A slow-starting server otherwise survives the failure path and keeps
the S3 port occupied for the next run.
