Refatora hook_install para carregar configs LDAP a partir dos YAMLs

Substitui a definição manual de valores no código PHP pela leitura dos
arquivos config/optional/ via FileStorage. Adiciona os YAMLs faltantes
(authorization.settings, ldap_servers.settings, ldap_authentication.settings)
e atualiza ldap_user.settings com os prov_module corretos.
