Myasnikov DaniilandClaude Opus 4.8 ff0d0d77a7 test(e2e): make the talos image cache reachable by tenant workers (#3254)
The in-sandbox Talos image mirror (#3244) is unreachable by the tenant
workers it serves, so the kubernetes-* e2e tests fail deterministically at
the 12m node-join wait instead of relieving the public-factory flake (#3231).

Root cause (from #3254 by @lexfrei, verified against the failing run's
crust-gather snapshot): tenant namespaces run a default-deny Cilium egress
(allow-internal/external-communication + the <tenant>-egress CCNP) that
permits the world entity and the tenant tree but NOT an arbitrary kube-system
Service, so a worker's CDI importer resolves talos-image-cache.kube-system.svc
yet its TCP connect to the ClusterIP is silently dropped and no disk imports.
#3244's gate never caught this because it probed the server over localhost
inside the serve pod, which passes regardless of cross-pod reachability.

Port of #3254 to the Chainsaw layout (hack/e2e-chainsaw/_lib/):
- ship a tightly-scoped CiliumClusterwideNetworkPolicy (importer pods in
  tenant-test -> mirror pod in kube-system), applied at point-of-use once
  Cilium CRDs exist; excluded from the pre-Cilium install apply via yq.
- replace the readiness probe with a throwaway pod in tenant-test labelled
  cdi.kubevirt.io=importer that curls the ClusterIP with a range request and
  must get 206 - the exact egress path a real importer faces; tenants use the
  mirror only when that end-to-end check passes, else fall back to the public
  factory, so it can only help, never make CI worse.
- unit test pinning the manifest split, probe/policy label agreement, the
  strict 206 gate, and the --overrides JSON builder.

Also adds (a2) DataVolume import-stage diagnostics to the node-join failure
block in run-kubernetes.sh (importer logs + a ClusterIP re-probe via
talos_image_cache_diagnose) so the import-stage failure mode is legible.
