Codex 1c4145a581 fix(ci1): swap bootOrder so Windows install ISO boots first ...

Original order: rootdisk=1 (empty 200Gi virtio), windows-iso=2 (SATA CDROM).
UEFI tried the empty virtio disk first, got nothing, fell back to Boot0001
(the SATA CDROM) with a short timeout, and aborted with:
  BdsDxe: failed to start Boot0001 ... Time out
  BdsDxe: No bootable option or device was found.

VM had been running 38+ min with rootdisk actualSize stuck at 4.13 GiB and
no AgentConnected condition — install never started.

Diagnosis via debug pod mounting the windows-server-2025-iso PVC:
  /pvc/disk.img: ISO 9660 CD-ROM filesystem data 'SSS_X64FRE_EN-US_DV9' (bootable)
  bytes 0..15: zeros (NOT QCOW2 magic 51 46 49 fb)
  bytes 32769..32773: "CD001" (ISO9660 primary volume descriptor)

So the PVC content is a real bootable ISO — the only fix needed is to make
the ISO bootOrder=1 for first install. After Windows installs, it writes its
own UEFI Boot#### entries pointing at the rootdisk EFI partition; UEFI then
boots from rootdisk going forward and the ISO at bootOrder:2 is a fallback
for re-install scenarios.
