## Why
The new `terraform-rancher` repo (manages Rancher's Authentik OIDC auth via the rancher2 provider) needs Vault auth + Consul state, mirroring the terraform-authentik runner (#78/#81/#82).
## Change
- `AppRole/terraform_rancher` + k8s auth role `woodpecker_terraform_rancher` (SA terraform-rancher in the woodpecker ns).
- Consul secret-backend role + ACL policy (`resources/secret_backend/consul_root/au/syd1/terraform-rancher.hcl`) granting write to the `infra/terraform/rancher/` state prefix.
- Vault policies: read the Rancher admin API token (`kv/service/terraform/rancher`) and the keycloakoidc client secret (`kv/kubernetes/namespace/cattle-system/default/oauth-credentials`), plus the consul_root state creds.
Scoped the OAuth read to the `cattle-system` path specifically (rather than the `+` wildcard the authentik policy uses) since the Rancher runner only needs its own app's secret.
## Validation
pre-commit (terragrunt-hcl-fmt + yamllint) passed. CI plan will confirm.

## Why
terraform-authentik's provider needs an Authentik API token (`TF_VAR_authentik_token`), now sourced from Vault at `kv/service/terraform/authentik` (Makefile wiring in terraform-authentik #2). The CI role needs read access to that path.
## Change
Extend `policies/kv/service/terraform/authentik.yaml` to also grant read on `kv/data/service/terraform/authentik` for the `terraform_authentik` approle + `woodpecker_terraform_authentik` k8s role.

## Why
terraform-authentik now reads OAuth2 client secrets from Vault (`data.vault_kv_secret_v2`) rather than committing them (terraform-authentik #2). But the `terraform_authentik` approle / `woodpecker_terraform_authentik` k8s role only had the consul-creds policy, so `plan` fails with permission denied on the grafana oauth path.
## Change
Add `policies/kv/service/terraform/authentik.yaml` granting read on `kv/data/kubernetes/namespace/+/default/oauth-credentials` for both the approle and the woodpecker k8s role.
