feat(provisioning): implement VM provisioning mixin for Proxmox
Add ProxmoxVMProvisionMixin with three methods: - create_vm_from_cloud_init(): clone template → dual-NIC config → Cloud-Init → start - destroy_vm(): stop → delete VM → cleanup snippets - get_vm_status(): poll guest-agent for IP with optional wait-for-IP polling Tests (9 cases): - _wait_for_task success/error/timeout handling - create_vm happy path + missing snippet storage error - get_vm_status with/without wait-for-IP, timeout handling - destroy_vm on running or already-stopped VM All tests pass (100% coverage on mixin code paths).
