feat: système multi-tenant (familles + inscription + invitations)

- docker/init/00-setup.sql : meta DB househub_meta (families + users) + grants
- docker/schema_family.sql : template DB par famille (toutes les pf_* tables)
- docker-compose.yml : MYSQL_DATABASE=househub_meta, init dir monté
- includes/meta_db.php : PDO vers househub_meta
- includes/db.php : connexion dynamique vers la DB famille (session)
- login.php : auth via meta DB + family_db en session + lien inscription
- register.php : inscription + création famille OU rejoindre via code
- invite.php : voir son code d'invitation + membres de l'espace
