feat: add support for dual frontend (JS and React) in the CCW application

- Updated CLI to include `--frontend` option for selecting frontend type (js, react, both). - Modified serve command to start React frontend when specified. - Implemented React frontend startup and shutdown logic. - Enhanced server routing to handle requests for both JS and React frontends. - Added workspace selector component with i18n support. - Updated tests to reflect changes in header and A2UI components. - Introduced new Radix UI components for improved UI consistency. - Refactored A2UIButton and A2UIDateTimeInput components for better code clarity. - Created migration plan for gradual transition from JS to React frontend.
