/**
 * OpenAPI route table — onboarding module tour.
 *
 * Part of the OpenAPI route table; aggregated in `./index.ts`.
 * The request schema comes from `src/lib/onboarding/tour-progress.ts`
 * so the wire contract stays single-source with the runtime parser.
 *
 * v1.18.6 — the resumable module-tour contract the iOS client mirrors:
 * a fire-and-forget progress checkpoint plus the coarse completion
 * flip. The resume point also rides `GET /api/auth/me` as
 * `onboardingTourProgress`.
