refactor(storybook): remove unused SW header demo stories

Remove nine SW/Header demo pages (property-fields, property-shape-slot,
composition, colorize, dynamic-controls, property-bar, additional-hover,
property-panel, layer-detail-input) and the demo code and Storybook-only
CSS used only by them. SW Stories 19 -> 10, total 338 -> 329.

The package runtime, public API, AI template and the retained Stories
(Overview, Dropdown, Property Panel 4-state comparison, Window Move
Motion and others) are unchanged. Add a current regression script and
mark the older scripts that open the retired IDs as historical evidence.
