Subject: [PATCH 2/2] test(seo): verify Person hydration and CSP contracts

Assert the enriched Person node on the static structured-data unit
tests, extend verify-prerender.mjs to check the localized
description/jobTitle and single canonical Person @id in the built
HTML, and add a real hydrateRoot integration test proving the
prerendered head reconciles to exactly one JSON-LD script with no
duplication.
