docs(storybook): simplify sidebar Story pages around the UI

Drop the category kicker from the 83 sidebar Stories (kicker is now optional;
hidden verification Stories keep it) and shorten or remove repeated, obvious
or internal page/section descriptions. Required specs, limits, virtual-data
and undecided-value notices stay. Story IDs, exports, fixtures, shared state
notes and package code are unchanged. Record: docs/reports/storybook-ui-simplification-2026-10-22.md
