test(journey-editor): add reorder tests, fix vacuous isDirty test, fix remove btn name

- Add move-up and move-down tests that verify PUT /items/reorder is called
  with the swapped ID order; 50ms delay accounts for two await levels before
  csrfFetch is called (click → handleMoveUp → handleReorder → csrfFetch)
- Replace vacuous 'isDirty stays false' test (was asserting a dialog that
  never renders) with a meaningful publish-button-enabled assertion after
  adding an item
- Update remove button query from 'Wirklich entfernen?' to 'Eintrag entfernen'
  to match the new journey_remove_item_aria aria-label
