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`.

 /**
- * OpenAPI route table — populated incrementally per W4 F5b and beyond.
+ * OpenAPI route table — populated incrementally.
  *
- * Routes are registered as `paths[<url>][<method>] = ZodOpenApiOperationObject`.
- * Schemas exported from `src/lib/validations/*` carry their own
- * `.meta({ id, title, description })` annotations so they show up in
- * `components.schemas` automatically when referenced via `ref:` or
- * direct schema inclusion.
+ * v1.4.23 baseline covers the routes the v1.5 iOS app touches end-to-end:
+ *   - POST /api/auth/login
+ *   - POST /api/auth/passkey/login-verify
+ *   - POST /api/auth/refresh
+ *   - GET  /api/measurements
+ *   - POST /api/measurements
+ *   - POST /api/measurements/batch    (W2 — Apple Health ingest)
+ *   - POST /api/devices               (W3 — APNs registration)
+ *   - GET  /api/insights/comprehensive
  *
- * The registry intentionally starts at zero coverage. Commit 2 of the
- * v1.4.23 W4 batch wires the iOS-touched routes; later waves expand
- * coverage organically. The CI gate at
- * `.github/workflows/security.yml` runs in `continue-on-error: true`
- * mode while coverage grows.
+ * Schemas come from `src/lib/validations/*` so the wire contract stays
+ * single-source-of-truth. The `.meta()` annotations on each schema land
+ * the title + description in `components.schemas.*` automatically.
+ *
+ * Routes are intentionally registered as inline operation objects
+ * rather than via a wrapping helper — `zod-openapi`'s `createDocument`
+ * type-checks the route table directly, which catches schema-shape
+ * regressions at typecheck time.
