Fix generator to produce proper client/server split React component structure

- Replace single HelloWorld.jsx with client/server split:
  - HelloWorld.client.jsx: Main component implementation
  - HelloWorld.server.jsx: Server-side wrapper importing from client
- Update react_no_redux_generator.rb to copy both client and server files
- This matches the proper_app_structure expected by React on Rails v15
- Enables proper SSR with separate client/server rendering paths

Fixes generator structure to match test expectations in base_generator_examples.rb
