Bind kubeconfig HTTP server to 0.0.0.0:8080 (was 127.0.0.1) so integration tests can reach it via QEMU SLIRP port forwarding. Add shared wait_for_boot and fetch_kubeconfig helpers to qemu-helpers.sh. Update all 5 integration tests to fetch kubeconfig via HTTP and use it for kubectl authentication. All 6 tests pass on Linux with KVM: boot (18s), security (7/7), K8s ready (15s), workload deploy, local storage, network policy. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
