feat(sw): viewer header logo menu and file list; simplify SW Storybook

SW Viewer Header (approved optional props, public export names unchanged at 170):
- SWViewerHeader: logoMenu, documents, activeDocumentId, onDocumentSelect,
  onDocumentOpen, documentOpenLabel; measured responsive toggles (full ->
  icons -> More) with the SWHeader More / file-list styling.
- SW AI guides, ExampleH, viewer/text-weight/theme-inheritance tests and the
  logo-document-menu tests with their QA record.

SW Storybook cleanup (Story IDs and test fixtures kept):
- Sidebar: Overview -> "SW Header" (first), 전체 Footer -> "SW Footer",
  Footer/Viewer responsive pages -> "Responsive More", Viewer content-variants
  -> "Settings Popup" (merges the settings popup page).
- Hidden by the verification tag (direct URL kept): Header Dropdown,
  Document Open, Interactive States, Document Dropdown, Hidden Sub Controls,
  Home Menu standalone; Footer tool groups / custom content / parts;
  SW/Theme; Viewer menu groups / item states / variable size / settings
  panel / Header + Dropdown.
- Removed demo UI: Overview size and callback output (demo data and
  selection only with &verification), Home Menu Figma node table and width
  demo, Header Responsive More reduced to 1440 / 768 / 390, Popup reopen
  button, property-panel comparison captions, Viewer context-menu demo
  (&verification only).
- Tests: storybook-inventory records the hidden and renamed Stories;
  overview / range-cross-browser / viewer open the demo controls with
  &verification; integrated-popup reloads the Story instead of the reopen
  button; dropdown-consolidation asserts Dropdown is hidden from the sidebar
  and still opens by its direct URL.
