 * Add `org_settings.allow_http_npm_registries boolean NOT NULL DEFAULT false`.

 * Operators flip this on a per-org basis to permit `http://` (non-HTTPS)
 * registry URLs in workflow `registries:` declarations. By default only
 * `https://` registries are accepted, with an automatic exemption for
 * loopback / `*.local` / private link-local hosts so dev fixtures
 * (Verdaccio at `http://verdaccio.local:4873`) keep working.
 *
 * Idempotent: a re-run on a DB that already has the column is a no-op.
