style(storybook): refine manager sidebar, LNB inset and shared story frame

- Manager sidebar labels and sort order for the grouped pages; LNB 1-depth
  text start 12px (token, baseline and LNB doc updated)
- Shared story frame: drop the divider under section titles, side margin
  max 60px -> 30px; Foundation color/typography spacing
- Pseudo-state mirroring also pins :focus-visible via data-sb-focus while
  keeping the previous clones for compound rules (Slider Focus + Drag)
