/**
 * @file AccountPoolCard.test.tsx
 * @description The Users page's account pool card: the pools board with every
 * tool's accounts (live panes and quota) and members per pool, then a tab per
 * tool with no pool — Oh My Pi's login sharing, and a "no pool" note for any
 * other installed tool; an
 * admin adds an account only with their own password typed (the token goes
 * in once and is not shown back) — a saved login moved in (the server's own
 * included), or a setup-token — and removes one the same way, and an analyst
 * sees no add or remove control. An account's Edit ticks the users who run on
 * it, saved with the admin's own password; the users show on the account.
 * The board moves members and accounts between pools (drag, or a column's
 * menu) — an account sits in one pool, so a move takes it out of the other —
 * splits an account off onto New pool, merges a pool by dragging its only
 * account into another, adds a saved profile to a pool, shows each account's
 * plan, and saves every change with ONE password.
