fix: disable UCAN log expiration (#416)

it looks like we set this bucket up to expire items - in retrospect I
think we should have created a separate bucket for the UCAN log because
this stream log store bucket was probably originally meant to store
streaming items temporarily

disable expiration for now, but uncomment with a note
