feat(post-install): catalogue de profils — paquets, Docker officiel, partages, VM tools (tâche 2 SJ-9)

- mécanisme presetVars (variables fixes injectées au rendu, surchargées par le formulaire)
- 6 profils : base_tools / network_tools / dev_git (listes de paquets, low),
  docker_official (dépôt officiel Debian, confirmation), sharing (Samba/NFS/mDNS, confirmation),
  vm_guest_tools (qemu/vmware)
- 4 templates custom (install-package-groups, docker-official-debian, sharing, vm-guest-tools)
  émettant PKG_INSTALLED/SERVICE_ENABLED/ERR → réutilise buildPostInstallResult
- l'UI post-install générique les expose automatiquement (manifeste → formulaire → run)

tsc 0 · 104 tests · build OK · boot OK (8 profils servis). Clôt le volet moteur tâche 2.
