(cURL) Disable ALPN

Usage Some web hosting providers have started using newer OpenSSL security settings that are currently incompatible with parts of Microsoft's authentication and Microsoft Graph infrastructure. On affected hosting platforms, such as IONOS and Fasthosts, this can cause Microsoft sign-in attempts or Microsoft Graph requests to fail unexpectedly with a "Not Found" (404) error. To prevent this issue, the plugin now automatically detects affected environments and enables a compatible configuration. This process is self-healing: if the issue is detected, the plugin will automatically enable the required setting without any manual intervention.
