/**
 * First-time / re-onboarding setup for the Deck Hearth Neon database.
 *
 * Pipeline (post-`migration-tool` convoy, 2026-05-26):
 *   1. Validate `ADMIN_INITIAL_PASSWORD` is set (fail loud BEFORE touching the DB).
 *   2. Spawn `npm run migrate up` to apply every pending migration under
 *      `migrations/`. The initial backfill migration (1779853647564_initial-schema)
 *      uses `CREATE TABLE IF NOT EXISTS` and is idempotent against fresh or
 *      pre-existing envs.
 *   3. Seed the admin user with `ON CONFLICT (email) DO NOTHING`.
 *
 * Make sure you have `POSTGRES_URL` set in `.env.local`. See README §
 * "First-time admin setup" for the operator runbook.
