After a power loss, minikube's Docker container (host) comes back up but
kubelet and apiserver remain stopped. The status check used
`--format='{{.Host}}'` which only examined the host state, causing the
role to skip `minikube start` since it saw "Running". Remove the format
flag so `minikube status` returns non-zero (exit 7) when any component
is unhealthy, and simplify all conditions to use the exit code alone.
