feat(k8s): add tuned network-latency deployment to post-setup

Browse Source 
Adds step to install tuned and set network-latency profile on all
k8s control-plane nodes during cluster bootstrap. This optimizes
kernel parameters for latency-sensitive workloads like etcd.

Also renumbers verification step from [3/3] to [4/4].
