Subject: [PATCH] Add setup-env.sh script for environment configuration

Creates interactive setup script that configures .env files for both
frontend and backend with the correct server IP address. Features:
- Auto-detects current server IP
- Prompts for custom IP if needed
- Checks for existing .env files before overwriting
- Configures REACT_APP_API_BASE, REACT_APP_API_HOST, and CORS settings

This prevents the issue where React apps start with localhost fallback
when .env files are missing or created after server startup.
