// Singleton per-instance (per-tenant) environment row for saltcorn-idp. Tracks
// first-run bootstrap state and an instance label for the admin UI.
//
// Stored in _sc_config (key CFG_ENV) rather than a _idp_env table: _sc_config
// survives backup and is restored BEFORE onLoad, so a restored instance keeps
// its env_id and onLoad does not create a duplicate (see lib/configStore.js).
