Site settings: fill schema.org organization data, drop scaffold examples

All seo.* settings now carry real values (sources: vitec.com footer + privacy policy, KBIS for the legal name VITEC SA): canonical base, org name/legalName, address Chatillon, phone, sameAs LinkedIn/YouTube, logo at fileadmin/vitec-brand/vitec-logo.png (served 200, verified in the home jsonLd as absolute www.vitec.com URL). Email left empty - no public address exists. Removed the my.vitec.setting / my.seoRelevantSetting scaffold examples from the set definition and the my.example.setting value.
