feat(07-01): wire global schema.org Person + WebSite and sitemap sources

- nuxt.config.ts: register 'nuxt-schema-org' module + sitemap.sources=['/api/__sitemap__/urls']
- app/utils/seo-person.ts: KILLIAN_PERSON_ID + killianPerson (derived from siteConfig, email excluded)
- app/app.vue: useSchemaOrg([definePerson(killianPerson), defineWebSite({name, inLanguage})]) appended (D-12)
- Verified SSR: /fr emits JSON-LD Person @id=#killian + WebSite (curl, pas d'hydratation)
