/**
 * Direct PostgreSQL escape hatch for setting up states the public API doesn't
 * expose — e.g. forcing a user into the locked-PIN state to assert the 429
 * recovery path, or expiring sessions for chaos tests.
 *
 * Most tests should NOT use this: prefer `ApiClient` so the tests exercise
 * the same code paths real users do. Reach for direct SQL only when the API
 * can't get you where you need to go.
