Adds the Flow rack lifecycle orchestrator (formerly RLA) helm chart at
helm/charts/nico-flow/, alongside the rest of the NICo subcharts. Flow
runs as a single pod with three gRPC containers — flow (50051), psm
(50052), nsm (50053) — sharing a SPIFFE cert and communicating over
headless Services that DNS-resolve to the pod IP. This mirrors the
upstream forged deployment.
Flow ships as a STANDALONE Helm release (release name "flow", namespace
"flow"), NOT as part of `helm install nico ./helm`. The nico umbrella
declares it as a conditional dependency with nico-flow.enabled defaulted
to false in helm/values.yaml — this keeps the chart in its conventional
helm/charts/ location while preventing Helm v3+ from auto-rendering it
into the nico release (where it would conflict with nico-prereqs over
the nico-system namespace).
Wires per-component dependencies into helm-prereqs so ./setup.sh brings
flow up end-to-end:
- postgresql.yaml: provisions flow/psm/nsm databases and roles on
nico-pg-cluster
- eso-external-secrets.yaml: ClusterExternalSecrets sync the
per-service DB credentials into the flow namespace
- flow-vault-tokens-job.yaml (new): post-install hook mints scoped
Vault tokens for psm/nsm and writes them as Secrets in the flow ns
- values.yaml: new flow.enabled / flow.namespace toggles; flips
vault.nicoApiK8sAuth.enabled=true (carbide-api requires the role)
setup.sh phase 7i deploys the chart with a pre-apply Certificate dance
to avoid cert-manager / FailedMount races, waits for vault tokens and
ESO DB-cred syncs, then helm upgrade --installs flow. clean.sh and
health-check.sh updated to cover the new namespace and resources.
The nico-flow Namespace template carries helm.sh/resource-policy: keep
so uninstalling flow does not wipe the prereqs-managed secrets that
live in the namespace.

Description
Adds a standalone helm-flow/ chart deploying the Flow rack lifecycle orchestrator (formerly RLA) as a single pod with three gRPC containers - flow (50051), psm (50052), nsm (50053). Mirrors the upstream forged deployment: containers share a SPIFFE cert and talk over headless Services that DNS-resolve to the pod IP.
Wires per-component dependencies into helm-prereqs so ./setup.sh brings flow up end-to-end:
setup.sh phase 7i deploys the chart with a pre-apply Certificate dance to avoid cert-manager / FailedMount races, waits for vault tokens and ESO DB-cred syncs, then helm upgrade --installs flow. clean.sh and health-check.sh updated to cover the new namespace and resources.

Additional Notes
helm-flow/ lives at the repo root (not under helm/charts/) so the nico umbrella does not auto-discover it as a subchart. The Namespace template carries helm.sh/resource-policy: keep so uninstalling flow does not wipe the prereqs-managed secrets that live in the namespace.
