refactor(vars): add system/hypervisor dict inputs

- Normalize new system_cfg + hypervisor_cfg and keep legacy vm_* and hypervisor_* aliases

- Support multiple system.disks (creation + optional mount + fstab generation)

- Add system_check safety role (production + existing system detection)

- Update README and example inventories
