 * Railway: post-install settings for an API-backed site (NEO client in front).
 * Runs from entrypoint.sh on every container start, after install, so it must be
 * idempotent. Plain mysqli on purpose: no UNA bootstrap, nothing cached yet.
 *
 * Environment:
 *   DB_HOST, DB_PORT, DB_NAME, DB_USER, DB_PASSWORD  set by entrypoint.sh
 *   UNA_API_KEY      key the NEO server proxy sends as `Authorization: Bearer`
 *   UNA_API_ORIGINS  comma-separated browser origins allowed to call the API directly
 *   UNA_CLIENT_URL   public client URL (links in emails and push notifications)
 *
 * Mirrors the "Database Configuration" and "New API Setup" stages of scripts/Jenkinsfile,
 * except that unsafe API services (raw SQL through r=q) stay off.
