apiserver: enable audit logging (low-write Metadata) + ship to Loki
Resource changes/deletions are now attributable (the novelapp deletion this week
was untraceable because apiserver audit was off). Low-write policy: drops
reads/noise, Metadata level on mutations, omitStages RequestReceived. Wired into
the kube-apiserver static-pod manifest + kubeadm-config (v1beta4
extraArgs/extraVolumes -> survives kubeadm upgrade) on k8s-master; Alloy tails
/var/log/kubernetes/audit/audit.log -> Loki {job=kubernetes-audit}.

Root cause that had silently blocked this AND OIDC for weeks: a stray
kube-apiserver.yaml.bak inside /etc/kubernetes/manifests/ was a duplicate
static-pod manifest kubelet ran instead of the real one, dropping every flag
added to the real manifest. Removed it. Runbook added.
