Viktor Barzin 124a756351 [infra] Adopt local-path-provisioner into Terraform (Wave 5c)
## Context

Wave 5c of the state-drift consolidation plan. `local-path-provisioner`
(Rancher's node-local dynamic PV provisioner) was deployed 55d ago via raw
`kubectl apply` against the upstream manifest. It serves as the cluster's
default StorageClass and is still actively in use — the 2026-04-18 live
survey showed helper-pod-delete cycles running against existing PVCs.

Unmanaged until now: namespace, ServiceAccount, ClusterRole (+ binding),
ConfigMap with provisioner config.json + helperPod.yaml + setup/teardown
scripts, StorageClass `local-path` (default), and the 1-replica
Deployment itself. Seven resources total.

## This change

New Tier 1 stack `stacks/local-path/` with all seven resources, adopted
via Wave 8's HCL `import {}` block convention (commit 8a99be11):

- `kubernetes_namespace.local_path_storage` → id `local-path-storage`
- `kubernetes_service_account.local_path_provisioner` →
  id `local-path-storage/local-path-provisioner-service-account`
- `kubernetes_cluster_role.local_path_provisioner` → id `local-path-provisioner-role`
- `kubernetes_cluster_role_binding.local_path_provisioner` → id `local-path-provisioner-bind`
- `kubernetes_config_map.local_path_config` →
  id `local-path-storage/local-path-config`
- `kubernetes_storage_class_v1.local_path` → id `local-path`
- `kubernetes_deployment.local_path_provisioner` →
  id `local-path-storage/local-path-provisioner`

Conventions applied:
- Namespace gets `# KYVERNO_LIFECYCLE_V1` marker suppressing the
  Goldilocks `vpa-update-mode` label drift (Wave 3B, commit 8b43692a).
- Deployment gets `# KYVERNO_LIFECYCLE_V1` marker suppressing the
  ndots dns_config drift (Wave 3A, commit c9d221d5 + 327ce215).
- ServiceAccount + pod spec pin `automount_service_account_token = false`
  and `enable_service_links = false` to match the live spec exactly.
- `import {}` stanzas removed after the apply converged to zero-diff
  (per AGENTS.md → "Adopting Existing Resources").

## Apply outcome

`Apply complete! Resources: 7 imported, 0 added, 3 changed, 0 destroyed.`

The 3 in-place changes were:
- `kubernetes_config_map.local_path_config.data` — whitespace/format
  reshuffle. The live ConfigMap contained the upstream manifest's
  hand-indented JSON + YAML; my HCL uses canonical `jsonencode` /
  heredoc. Semantic content identical, so the provisioner continued
  running (no pod restart).
- `kubernetes_deployment.local_path_provisioner.wait_for_rollout = true`
  — TF-only attribute, no cluster impact.
- `kubernetes_storage_class_v1.local_path.allow_volume_expansion = false`
  + `is-default-class` annotation re-asserted — TF-schema reconciliation
  only; the StorageClass remained default throughout.

Post-apply `scripts/tg plan` returns `No changes`.

## Verification

```
$ cd stacks/local-path && ../../scripts/tg plan
No changes. Your infrastructure matches the configuration.

$ kubectl -n local-path-storage get deploy
NAME                     READY   UP-TO-DATE   AVAILABLE   AGE
local-path-provisioner   1/1     1            1           55d

$ kubectl get sc local-path
NAME                    PROVISIONER              RECLAIMPOLICY   VOLUMEBINDINGMODE
local-path (default)    rancher.io/local-path    Delete          WaitForFirstConsumer
```

## What is NOT in this change

- Helm-release adoption — local-path-provisioner was never installed via
  Helm in this cluster; raw manifests only. Keeping native typed
  resources rather than retrofitting a chart.
- PV-path customisation — sticks with upstream default
  `/opt/local-path-provisioner` on all nodes (via
  `DEFAULT_PATH_FOR_NON_LISTED_NODES`).

Closes: code-3gp
