## Why
The deployer identities cannot enable the `oidc` auth mount: `POST /v1/sys/auth/oidc` returns 403 because `sys/auth/<path>` (and its `/tune`) is sudo-protected, and `policies/sys/auth/admin.yaml` granted create/update/delete/read/list without `sudo`.
## How
- Add exact-path rules for `sys/auth/oidc` and `sys/auth/oidc/tune` to `policies/sys/auth/admin.yaml` with the wildcard's capability set plus `sudo` (exact match wins over the glob, so the set is repeated in full); auth block unchanged.
Merge order: apply this, then re-run the master apply so `module.auth_oidc_backend["oidc"]` can create the mount.

## Why
Wiring the new Rancher token secrets engine into Vault. The deployer registers the plugin (sudo-protected `sys/plugins/catalog`) and configures the engine via the ranchervaultsecret provider, so it needs catalog + engine-path access. Mirrors #88 (gpg).
## Changes
- Add `policies/rancher/admin.yaml` granting the `tf_vault` approle and `woodpecker_terraform_vault` k8s role: catalog sudo on `vault-plugin-secrets-rancher`, and manage on `rancher/{config,service-accounts,roles}`.
## Merge order
Part 1 of 4. Merge before the plugin-import and backend PRs so apply doesn't 403. (Puppet install + this policy first, then import, then backend.)
