/**
 * @file server-mode-user-edit.test.js
 * @description The Users page's Edit user form (`GET`/`PATCH /api/users/:id`)
 * and Settings → Account (`/api/me/account`, `/api/me/password`,
 * `/api/me/sign-out-others`): one PATCH validates every field before any is
 * written, sets display name/email/role/password/workspaces/sign-out together
 * with the admin's own password, never takes a workspace from a third user; a
 * user edits their own profile, changes their own password only with the old
 * one (keeping the login they changed it from), signs out other devices, and a
 * pane token may not do any of it.
