fix(helm): use /host prefix for CNI config path in container

The Helm template was hardcoding configPath: /etc/cni/net.d which
overrode the auto-detection logic in the Go code. Since the host
filesystem is mounted at /host in the container, the CNI config
path needs to be /host/etc/cni/net.d.

This fixes CNI health checks showing False even when CNI is healthy.
