The sudo-rs section claimed the whole fleet runs the stock "wheel, with a
password" policy, which is no longer true for the WSL host. Explain why the
NixOS-WSL default does not survive the sudo-rs swap, and mark the difference in
the per-host table.
NixOS-WSL sets `security.sudo.wheelNeedsPassword = false`, but that option
belongs to the `security.sudo` module and does not carry over to the sudo-rs
swap in modules/common-nixos.nix, whose equivalent option defaults to true.
Since that swap landed, sudo on this host prompts for the account password --
which WSL set during install and nobody knows -- so escalation only worked
through `wsl -u root`.
Set `security.sudo-rs.wheelNeedsPassword = false` on the host to match the
NixOS-WSL default. Other NixOS hosts are unaffected and keep the prompt.
