Subject: [PATCH] pxe: ship Ubuntu iwlwifi firmware with the Blancco kmod
 tarball

The UEFI Blancco path boots the Ubuntu 6.8 kernel on Blancco's rootfs, so
iwlwifi loads firmware from the Blancco image. 7.20 dropped the API 86
ucode for AX201/AX210/AX211 and ships only API 89, which the 6.8 driver
cannot use: WiFi never came up, so no cloud licence (seen 2026-10-05).

kmod.tar.gz now also carries the host's lib/firmware/iwlwifi-* (183
files, .zst, which the kernel prefers over the image's .xz). Files only:
on the Blancco rootfs lib is a symlink to usr/lib. Live tarball rebuilt
(backup kmod.tar.gz.bak-20261005-pre-iwlfw); the task's creates: guard
means an existing server needs the file removed to pick this up.
