"""
Admin Settings page tests.

Scenario 7: after a config change that does not involve a container restart
pathway (e.g. NTP servers), the pending-restart banner defined in App.jsx
('Configuration changes pending — containers need restart') should appear.

The pending-restart banner text (from App.jsx PendingRestartBanner):
  "Configuration changes pending — containers need restart"
  Buttons: "Discard" and "Apply Now"

Because the exact form field structure in Settings.jsx may vary, tests
that interact with form inputs are marked xfail with a tuning note.
Tests that only verify the banner renders given a pre-seeded pending state
are stable and always run.
