/**
 * @file MemberTmuxCard.test.tsx
 * @description The Users page's members' tmux card: hidden without one Linux
 * user per account, lists each running member server with its version and a
 * badge when it is older than the installed tmux, warns until tmux-member is
 * installed, and an admin restarts one member — or every idle outdated one,
 * the working member left out — only with their own password typed; an
 * analyst sees no restart control.
