feat: warn when no reporting destination is configured

report exits zero and writes bodies for a case with only abuse-desk
contacts, since that is a perfectly good report on its own. But a user
who believes MISP is configured and finds no misp row has a typo'd
section name, and MISP gates everything irreversible, so a stderr
warning naming the config path catches that before submit time.
