feat(sw): refine viewer model layout design and theme tokens

- Model / Layout tabs follow Figma 7652:40344: gradient faces, gold / green
  gradient borders, blurred outline, inner shadow and top gloss, with every
  color in its own --hm-sw-viewer-tab(s)-* token (consumer-overridable)
- Box height matches the adjacent field group (42px, from the control height
  token); padding 1px 1px 1.5px, button side padding 5px, 1px right margin
  for a tabs-only first group; 378px max width, equal buttons and the
  measured More steps are unchanged; existing text-shadow kept
- Storybook: SW/Viewer > Model / Layout story (states and token override);
  Logo story listed before Responsive More
- AI docs (VIEWER.md, DESIGN_RULES.md) and viewer / text-weight test
  expectations updated

 - **높이:** 패키지는 뷰어(도면) 영역 높이를 정하지 않습니다. Header는 52px 한 줄, 팝업만 최대 90vh입니다. 화면 높이는 앱의 상위 레이아웃이 정하고(예: `html, body, #root { height: 100% }` → 세로 flex, Header 다음 도면 영역 `flex: 1; min-height: 0`), 도면 영역 크기 변화에 맞춰 렌더러 크기를 바꾸는 것은 프로그램 담당입니다(ResizeObserver 권장). Storybook 예시의 고정 높이는 미리보기 프레임 값일 뿐 컴포넌트 값이 아닙니다.
 - Light/Dark 분기는 없습니다. 참고 뷰어와의 알려진 차이: 도면 공간(tabs) field 면 높이 42px(참고 41px — 참고 Tabs 루트가 39px인 구현 부산물), 크기 조절은 네이티브 `resize` 대신 같은 위치의 모서리 Grip(모든 브라우저 동작), 패널 Escape 닫기 추가, 로고 기본 표시 없음(사용자 결정).
