CHW-1406 BillingStoreUnavailable

billing store is not available; the server started without a database — check the operator dashboard

Default message: billing store is not available; the server started without a database — check the operator dashboard
HTTP status: 503 (server)

Problem. A billing read endpoint returned 503. Cause. The server started without a database connection, so billing DAL calls cannot run. Fix. Ask the operator to wire a Postgres connection and restart. HTTP 503.
