/**
 * Guards the one thing about Payload's mounting that fails silently.
 *
 * payload.config.ts itself cannot be imported here — Payload is ESM-only and
 * next/jest will not transform it — so this asserts the shared constants and
 * that the config actually wires them in, by reading its source. The live
 * proof that /api still reaches FastAPI is the e2e journeys, which call
 * /api/schools against the running app.
