prepare neuron-tim namespace for Tim's future Neuron instance

Adds the neuron-tim namespace (via Terraform) and a full Argo CD
app + k8s manifests mirroring neuron-prod. All deployments set to
replicas=0 — nothing runs until Tim's imprint is ready and Vault
secrets are populated at secret/neuron-technologies/tim.
