fix(tests): update issue page tests for new header and view store shape

- Add missing view-store mock fields (sortBy, sortDirection, cardProperties,
  listCollapsedStatuses, toggleListCollapsed) and exported constants
- Add SortableContext mock to @dnd-kit/sortable
- Fix filter button assertions (Status/Priority: All → Filter/Display)
- Fix issue detail test: use getAllByText for duplicate title text
- Fix breadcrumb test: workspace name shown instead of "Issues"
