fix(dozzle): add nodes permission to ClusterRole for k8s mode

Dozzle running in k8s mode requires permission to list nodes at cluster
scope. Without this permission, the pod fails with error:
"nodes is forbidden: User \"system:serviceaccount:dozzle:dozzle\" cannot
list resource \"nodes\" in API group \"\" at the cluster scope"

This change adds the nodes resource with get, list, and watch verbs to
the ClusterRole, allowing Dozzle to discover all nodes in the cluster
when running in k8s/swarm mode.

Resolves: DEV-349
