## Why
Four newly-provisioned el9_8 compute nodes (prodnxsr0014/0015/0018/0019) hang with canal's kube-flannel container in `ImagePullBackOff`: the flannel VXLAN overlay never comes up, so the node can't reach any in-cluster `198.18.200.x` LoadBalancer VIP.
Root cause is a stale airgap-preload version. The nodes boot rke2 **v1.33.11+rke2r1** from the rolling `latest/1.33` repo, whose canal manifest requests `hardened-flannel:v0.28.4` / `hardened-calico:v3.31.5` (build20260415). But `rke2::install` pinned the preloaded bundle to **v1.33.4+rke2r1** (flannel v0.27.2 / calico v3.30.2), so those images were never on disk. containerd then falls back to the `docker.io` mirror (artifactapi, `disable-default-registry-endpoint: true`), reachable only via the pod-overlay VIP that requires the very flannel image being pulled — a bootstrap deadlock. Older nodes (0001-0008) are versionlocked at 1.33.4 and still match their original bundle, so they were unaffected.
## Changes
- Bump pinned `rke2_version` `1.33.4` -> `1.33.11` so the versionlock, RPM `ensure`, and preloaded bundle all line up with the canal image tags the running binary requests. The default `rke2-images.linux-amd64.tar.zst` bundle already contains the canal CNI images (it is RKE2's default CNI), so no extra tarball is needed.
- Wire the airgap archive `source` to the `container_archive_source` class parameter (previously declared in the module but never consumed). The module keeps its generic upstream default; the artifactapi override (the pre-CNI-reachable source, same BGP/physical path the rke2 yum repos already use) lives in the k8s role hiera as `rke2::container_archive_source`.
Applies to servers and agents alike (`rke2::install` runs for both) and preloads `before => Service`, so the bundle lands before rke2 starts.
Notes:
- The `latest/1.33` repo is rolling, so the pinned version must be maintained as the repo advances; a follow-up to pin the yum channel to a fixed patch would remove the drift entirely.
- No terraform-artifactapi change is required. (If a canal-only preload were ever wanted, the github generic remote allowlist would need `rancher/rke2/.*/rke2-images-canal.linux-amd64.tar.zst$` added — but the default bundle already carries those images, so it is unnecessary.)
