Keep sw-header--property-panel-compare as the single property panel state
page: the four existing SWHeaderPropertyPanel states in 2 columns x 2 rows
at their original size, inside a scrolling Inner. Remove the duplicate
Property Panel Variants and the four single-state Stories (SW 24 -> 19).
Storybook-only change; SW runtime and public API untouched.
