feat(sw): integrate responsive home menu into header

- Merge SW / Home Menu Stories into SW / Header (sidebar: Home Menu; others verification-tagged)
- Home On: logo hover ring and header top/bottom #5F4B0F lines while the menu is open
- Measured More in SWHeader; home menu narrow widths use a More (...) section with a grouped
  text menu instead of horizontal scroll, placed right after the last visible section
- Action tiles no longer stay on after a click; 최근파일 stays Active only while its list is open
- More dropdown and recent files list never open together; list top joins the accent line
- Recent files preview falls back left / over the list at narrow widths (390px)
- Update Storybook, browser tests, docs, AI guides and QA evidence
