♻️ refactor(hosting): Remplace l'hébergement Google Cloud Platform par OVHcloud (datacenters France) sur les pages légales et hébergement.

- legal.twig (section 3 Hébergement du Site) : Google Cloud Platform → OVHcloud, adresse Mountain View → 2 rue Kellermann Roubaix.
- hosting.twig (section 1) : renomme Infrastructure Cloud → Hébergement du Site, badge eu-west4 → France.
- Traductions (fr/en/es/cn/ger) : hosting_infrastructure_title, hosting_cloud_provider, hosting_location_detail, legal_host_address, legal_host_data_location, hosting_compliance_desc, et nettoyage des clés orphelines hosting_section1_p1, hosting_data_location_details, hosting_contact_details.
