 * `f12_cf7_doubleoptin_register_addons` fires at plugins_loaded:20,
 * giving addons their chance to register migrations before they run).

 * Running only on `admin_init` keeps DDL out of the frontend request
 * cycle: migrations apply when a site admin visits the admin, which is
 * the same trigger WordPress core uses for database upgrades.
