// Singleton per-instance (per-tenant) environment row for saltcorn-idp. Tracks
// first-run bootstrap state and an instance label for the admin UI.

// No module-level cache: in multi-tenant mode a single un-keyed cache would
// serve one tenant's row to another. Reads are infrequent (onLoad + dashboard),
// so we query each time within the caller's tenant context.
