The chart generated the login RSA keypair on every render, so
checksum/secret-login-service-key changed each time and both Zitadel
Deployments stayed permanently OutOfSync.
Adopt the live keypair into k8s/argocd/secrets/zitadel-login-service-key.enc.yaml
(SOPS, age recipient from .sops.yaml), list it in the ksops generator, and point
login.loginServiceKeySecretName at it. The chart then stops generating the
keypair and the Deployment checksums become deterministic.
