Implement auto-generation of ecosystem.config.js and improve container setup

- Add automatic ecosystem.config.js generation from package.json
- Create app directory automatically if missing
- Copy simple-website example when app directory is empty
- Remove redundant default app files from configs/
- Add HAProxy support with proper real IP forwarding
- Configure nginx to trust proxy headers from private networks
- Simplify entrypoint logic - always use /home/$user/app

This makes the container more user-friendly by eliminating the need for
manual PM2 configuration and ensuring the server always has a working app.
