feat(openapi): register iOS-touched routes from Zod schemas

Wires the v1.4.23 baseline route table — auth/login, passkey verify,
refresh, measurements GET + POST + batch, devices POST, insights
comprehensive — into the new generator. Schemas reuse the existing
validation files via Zod v4's `.meta()`, so the iOS DTO contract stays
single-source-of-truth.

The freshly emitted spec covers ~880 lines (down from the 5468-line
hand-maintained legacy preserved in `openapi-v1422-legacy.yaml`).
Future routes get added incrementally via `src/lib/openapi/routes.ts`.
