feat: migrate vso-system to ArgoCD

Migrate Vault Secrets Operator from Terragrunt to ArgoCD/Kustomize.
Deploys vault-secrets-operator v1.2.0 with 3 replicas, plus ClusterRole,
ClusterRoleBindings, and vault-admin ServiceAccount.

Note: static service account tokens (kubernetes.io/service-account-token)
cannot be stored in git; create manually or via Vault after deployment.
