Remove unused React logo SVG and add new API client and layouts

The React logo SVG file was removed as it was no longer needed. Introduced an auto-generated API client class (`ApiClient.ts`) for handling server communication and added new components for the navigation menu and higher-order layouts (`NavMenu`, `with_main_layout.ts.tsx`). Updated `yarn.lock` to replace legacy URL references.
