Virtual Machines: reinstall from a new OS

The new Reinstall tab on a VM lets you wipe the root disk and reinstall a fresh OS (same template or a different one - Ubuntu, Debian, Rocky, Alma, CentOS Stream, Alpine, and more). VM identity, name, networks, IPs, MAC, security groups, attached volumes, floating IPs and login credentials all stay put; only the root filesystem is replaced. Pick the template, type the VM name to confirm, choose between graceful or force stop, and watch the progress live (stopping → wiping → cloning → booting). Existing snapshots and backups of the reinstalled VM become orphaned, as expected.
