chaosinthecrd 97a75c837d cmd/k8s-operator,ipn/store/kubestore,kube/kubetypes: share ACME account key per tailnet
Introduce a per-tailnet shared ACME account key so that all ingress
ProxyGroup replicas on a tailnet present the same account identity to
Let's Encrypt. This lets renewals claim the ARI "replaces" exemption
from the 50-certs-per-week rate limit, surviving Pod restarts,
ProxyGroup recreation, and cluster migrations.

The operator provisions a "tailscale-acme-accounts" Secret in its
namespace, guarded by a finalizer and a deletion warning event, and
watched so it is recreated promptly if removed. Proxies migrate any
pre-existing per-pod key into the shared Secret on first boot, adopt
the shared key on subsequent boots, and restore it on cert writes if
the Secret was recreated empty. Certs are stamped with the fingerprint
of the issuing account so renewals skip the "replaces" claim when the
account doesn't match.

Opt-in per-ProxyGroup via the tailscale.com/share-acme-account
annotation, or operator-wide via OPERATOR_SHARED_ACME_ACCOUNT_KEY.
