+start metrics polling before certificate provisioning to avoid blocking metrics collection
+
+- Start metrics polling immediately after Rust engine startup so metrics are available without waiting for certificate provisioning.
+- Run certProvisionFunction after startup because ACME/DNS-01 provisioning can hang or be slow and must not block observability.
+- Code change in ts/proxies/smart-proxy/smart-proxy.ts: metricsAdapter.startPolling() moved to run before provisionCertificatesViaCallback().
