chore(storybook): refine navigation and foundation labels

- Rename Foundation/Typography to 폰트 and SW/Footer to SW/하단 명령어바 in
  the sidebar order; Story IDs are kept (foundation-typography, sw-footer).
- Hanmac Color: label Light 4 as "보더 하이라이트용" and add a divider between
  Light 4 and Light 3.
- Hide Patterns/Layout/Page Header from the sidebar with the verification tag
  (Story IDs and direct URLs are unchanged).
- Remove the Variants section from the representative LNB page; With Logo and
  Long Labels remain as verification Stories.
