Configure flexible deployment with environment variables

- Change Flask port from 8080 to 5000 for consistency
- Add environment-based network mode configuration (bridge/host)
- Support both Windows Docker Desktop and Linux LXC deployments
- Remove obsolete docker-compose version and conflicting network settings
- Add .env.example with platform-specific configuration guidance
