Fix create events rbac

[enrichman]

This PR fixes the error from the Virtual Kubelet trying to create Events without the needed RBAC:

2025-11-21T16:53:19.228Z    ERROR    Server rejected event (will not retry!)    {"event": {"namespace": "ns-dg96l", "name": "cluster-b9k9s.187a13d2948bb5ac"}, "error": "events is forbidden: User \"system:serviceaccount:ns-dg96l:k3k-cluster-b9k9s-kubelet\" cannot create resource \"events\" in API group \"\" in the namespace \"ns-dg96l\""}

It also cleanup the virtual kubelet logs, in order to have a more consistent flow with the same structured values, and logs in the errors.
