Fleet-wide host config drift detection for Scaleway Apple Silicon

The Scaleway Apple Silicon CAPI provider’s drift loop now re-pushes host configuration to existing Mac minis whenever anything in the host configuration changes, not just when the tart-kubelet binary changes. This means fleet-wide changes such as install scripts, firewall or NAT settings, Tailscale or node_exporter binaries, and fleet CIDR/tags/accept-routes will now roll out to already-provisioned hosts automatically on the next reconcile. The first reconcile after upgrading will re-push once to existing machines, applying the latest configuration without downtime. This closes a gap where script-only or fleet-config-only fixes previously required manual SSH updates or forced CR patches to reach existing hosts.
