User-domain natives. Wraps server::command::VerifyUserPassword only;
account-creation/registration is reserved for the auth-flow path, not the
eval channel.
verify-user-password is exposed verbatim from the server command —
takes (email, password), returns the matching UUID on success or nil
on bad creds. The session is already authenticated by the time forms
reach the eval channel, so this native exists for “confirm current
identity before sensitive action” workflows the emacs client may
drive (e.g. re-prompting on session-reauth UX).
