The archived-config reactivation path in createConfig returned before the
MAX_CONFIGS_PER_PROJECT check, so re-adding previously archived domains
could push a project past the active-config cap (Codex security finding
ba873417). The cap check now runs before both the reactivation and the
new-row insert. Also raises MAX_CONFIGS_PER_PROJECT from 100 to 500.
