fix(ai-judge): wrap advice widget lines instead of truncating

- replace render-time truncation with wrapTextWithAnsi so the full
  reason stays visible on narrow terminals and CJK text
- cap content length only at the sanitize layer, never at render
- verify wrapping preserves reason content in tests
