style(storybook): tidy CENTER, chart, org chart and SW story pages

- CENTER plain page layout and shorter reference demo notes (spec values
  moved to the CENTER README); chart specimen descriptions trimmed
- Org chart page names and previews; SW width rows follow the 30px frame
  margin (1980 / 1065 / 727px) and the SW tests match the current layout
- Story inventory regenerated and WORKING_CONTEXT updated
