cproudlock ade2f3b5ff Fix USB install reliability: bash, LV resize, deps, idempotency
- autoinstall/user-data: move lvextend/growpart/pvresize BEFORE playbook
  so 130GB of drivers+PPKGs fits during first-boot copy. Use
  tr -d "[:space:]" to avoid breaking outer bash -c single-quote wrap.
- playbook: add executable: /bin/bash to Dell driver deploy (process
  substitution) and Blancco initramfs builder (brace expansion).
- playbook: make "Ensure Samba user for Blancco reports" idempotent via
  pdbedit check so re-runs don't abort the play.
- download-packages.sh: also download dist-upgrade package set. Explicit
  --simulate misses transitive version bumps (e.g. gnupg 17.4 needs
  matching gpgv 17.4) causing offline dpkg "dependency problems" when
  ISO baseline is older than noble-updates.

# The PXE server installs Ubuntu 24.04 (Noble), so all packages MUST come from the

# it auto-spawns an Ubuntu 24.04 docker container to do the download.

# ./download-packages.sh [output_directory]
