feat(terraform): Create VMs from scratch with Ubuntu 24.04 cloud image

Changements majeurs:
- Supprime le clonage de template (clone/full_clone)
- Utilise l'image cloud Ubuntu 24.04 LTS directement
- Ajoute os_type = cloud-init pour support natif
- Configure Standard VGA pour compatibilité
- CPU type host pour meilleures performances
- BIOS seabios explicite

Avantages:
- Proxmox crée automatiquement les ressources LINSTOR
- Plus besoin de script Python de pré-provisioning
- Pas de dépendance sur template pré-existant
- Configuration via cloud-init uniquement

Pré-requis:
- Télécharger ubuntu-24.04-server-cloudimg-amd64.img sur chaque nœud
- Placer dans /var/lib/vz/template/iso/
