/**
 * @file InterruptedSessionsPrompt.test.tsx
 * @description The "resume interrupted sessions?" dialog: it opens only when
 * the server lists some, resumes only the ticked ones (never a bypass mode
 * carried over), and either answer dismisses the list — but a resume that
 * failed stays offered.
