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).
