fix(tests): resolve 9 CI test failures in journey-editor specs

- useBlockDragDrop: add runtime expect() alongside expectTypeOf so
  browser-mode runner counts at least one assertion
- JourneyAddBar: use exact:true on 'Hinzufügen' button — partial match
  was hitting '+ Brief hinzufügen' and '+ Zwischentext hinzufügen' too
- JourneyEditor: fix 4 issues — drop wrong not.toBeInTheDocument()
  (placeholder creates accessible name); pass title:'' in publish-disabled
  test (default was non-empty); use getByPlaceholder for interlude
  textarea to avoid 4-element strict-mode violation; exact:true for
  'Hinzufügen' button
- DocumentPickerDropdown: use .click({force:true}) on aria-disabled
  option — userEvent refuses non-enabled elements
