Add the concept's shared page toolbar (search.toolbar with the search
field, category filter, sort and Filters) and its dialogs in one modal
shell: "Refine this view" (Source / Folder / Media / Tags, Apply filters),
"Import & inspect" with only the real operations (Open inspector, Rescan),
and the "Copy prompt" select-to-copy fallback. The sort lists the
concept's three options first (D14); there is no Save view (D16). Every
dialog returns focus to its trigger on close or Escape.
