/**
 * Single user list row in the admin user management section.
 *
 * Whole row is keyboard-activatable as a button (Enter / Space → edit
 * mode) since the click target is a `<div>` rather than a real button —
 * we need nested action buttons (magic string, delete) and a `<button>`
 * inside a `<button>` is invalid HTML.
 *
 * The library-names column is built from the union of the user's
 * libraryIds and the live libraries list, so it stays in sync if the
 * admin re-assigns libraries elsewhere.
