Move two zero-coupling icon components out of the editor into the shared SUI
library (frontend/shared/components), export them from the barrel, and add
Storybook stories. Editor consumers now import them from @shared instead of
@app. Both are fully self-contained (pure SVG, no app context, inline colours /
caller-supplied className), so the move is mechanical and nothing else changes.
First slice of an incremental extraction; it establishes the move + re-point +
Storybook pattern to repeat for further components.
