fix: lock down application form when intake round is not active

getConfig now throws FORBIDDEN when round is not ROUND_ACTIVE,
preventing the form from loading entirely. Also blocks draft
saving when round is inactive. Defense-in-depth: submit already
rejected inactive rounds, this adds the frontend gate.
