It breaks when regex type in `consent.disable` exists

When you have ['type' => 'regex', 'pattern' => '/.*\.mycompany\.com.*/i'], in consent.disable variable in config breaks the module.

The relevant line: https://github.com/simplesamlphp/simplesamlphp-module-consentadmin/blob/799cc2096c379a29fc90d1cd711e29718955a224/src/Controller/ConsentAdmin.php#L206

There is no type check for $disable variable.

        // Remove services, whitch have consent disabled
        if (isset($idp_metadata['consent.disable'])) {
            foreach ($idp_metadata['consent.disable'] as $disable) {
                if (array_key_exists($disable, $all_sp_metadata)) {
                    unset($all_sp_metadata[$disable]);
                }
            }
        }

从 src/Controller/ConsentAdmin.php 中链接的行开始，检查每个 consent.disable 条目包含所示 regex 配置时是如何处理的。使用该配置复现故障，然后验证模块不再出错，并且预期的服务过滤仍然有效。
