docs(storybook): tidy SW Storybook gauges, responsive rows and page titles

- SWPopup Custom Content and the SW Viewer options panel use SWSlider style B
  (appearance="property") only; the A/B comparison, the style select and the
  green panel gauge are gone (SWViewerSlider itself is unchanged).
- SW Header / Viewer / Footer Responsive More: the 1920px row shows only when the
  content Inner is 1920px or wider (container query); Footer rows fit the page
  width without scrollers so ▲ More handles narrow widths.
- Logo pages fit without scrollers; SW Header Logo Slot is "Logo" in the sidebar
  with the title "SW Header — 로고" (ID sw-header--logo-slot kept).
- Property Panel (was "Property Panel · 4개 비교"): no Inner scroller, the page
  scrolls, 2 × 2 grid with one column below 720px.
- SW Footer drops the "실제 Footer 조합 (동작)" heading; SW Viewer Header page is
  titled "SW Viewer Header" with 기본형 and 최소화 · 닫기 버튼 only.
- Browser tests, inventory and README follow these changes; visual baselines are
  not updated.
