fix(ci): run Storybook for UI source changes

[Astro-Han]

Summary

Run the Storybook build and smoke job when packages/ui/src/** or apps/desktop/src/renderer/** changes. Product stories mount both source surfaces, so runtime export and render regressions can break the catalog without touching a story file.

The previous catalog-only selector let #2538 add the non-component ICON_SIZE export without running the icon catalog, and let #2546 change the Daily Review selector geometry without running its narrow layout contract. A later unrelated full-suite change discovered both failures on main.

Refs #2541

Verification

• RED: node --test scripts/ci-test-plan.test.mjs failed because UI and renderer source changes returned storybook=false.
• GREEN: node --test scripts/ci-test-plan.test.mjs — 6/6 pass.
• npx biome check scripts/ci-test-plan.mjs scripts/ci-test-plan.test.mjs

Dependencies

This draft intentionally exposes the two Storybook failures already present on main:

• fix(storybook): filter non-component icon exports #2544 filters non-component icon exports.
• fix(desktop): bound settings selector menus #2556 bounds settings Selector menus across font metrics.
• Rebase after both fixes merge and verify the newly selected Storybook job is green.

Checklist

• Tests cover the change and fail without it
• Lint, format, typecheck and the affected suites pass locally
