## Why
AppRole capabilities are fixed at login, so the deployer needs `auth/oidc/*` and identity-group grants in an apply that precedes the one creating those resources.
## How
- Add `policies/auth/oidc/admin.yaml`: full `auth/oidc/*` administration (mount config and login roles), mirroring `policies/auth/ldap/admin.yaml`.
- Add `policies/identity/group/admin.yaml`: manage external identity groups, group aliases and `identity/lookup/group`, on both the collection and per-id endpoints.
- Grant both policies to the `tf_vault` approle and the `woodpecker_terraform_vault` k8s role.
