Add optional Cloud-Init and q35 support

Introduce optional Cloud-Init integration and better machine type handling for VMs. Changes include: loading cloud-init helpers lazily (load_cloud_init_functions), interactive cloud-init prompt/configuration (vm_prompt_cloud_init) and SSH key handling, a cloud icon for UI, and vm_machine_type_label for readable machine type display. Default machine type switched to q35 and displays the label in prompts and summaries. VM creation logic now conditionally attaches the cloudinit drive (ide2) and runs setup_cloud_init when enabled; otherwise it creates the VM without the cloudinit device. Post-install messaging now either shows cloud-init details or a guidance message about manual guest filesystem expansion. Minor UI/output adjustments and defaults updated accordingly.
