fix storybook deploy

What does this pull request change?

• fix imports of Layout which is a circular dependency. Storybook seems to split bundle the code and serving from http-serve or nginx fails.
• fix default import in style.js which has incorrect syntax, default export of object is invalid syntax, and fails the bundle generated by storybook. Ref https://www.ecma-international.org/ecma-262/6.0/ 15.2.3
• fix nginx and dockerfile setup
