test(storybook): Playwright suite for full Storybook + Spotify/Discord polish

- Add playwright.config.storybook.ts: runs against storybook-static on :6007
- Add e2e/tests/storybook/storybook-all.spec.ts: one test per story (load iframe, no errors)
- Add scripts/serve-storybook-static.cjs: serves build or stub (empty index) when no build
- npm run test:storybook:playwright (after build-storybook) for full coverage
- Storybook decorator: use bg-background / design tokens for dark (#121212)
- Preview: default dark background #121212
- Button: secondary/ghost/glass aligned to Spotify/Discord (white/5, white/10 hover)
- KodoEmptyState: softer orbs, compact copy, primary CTA without heavy glow
