// End-to-end smoke: bootstrap → accept pending host → run backup → see succeeded.

// agent in announce-and-approve mode. This test drives the operator
// path through the UI (login + dashboard) and the API
// (accept + run-now + poll for terminal) — UI for the human surfaces,
// API for the deterministic ones.
