Add Docker networking support for N8N and container integration

- Added docker-compose.api-localai.yml for Docker network integration
- Updated config.py to support dynamic Supabase connection strings via environment variables
- Enhanced documentation with Docker network deployment instructions
- Added specific N8N workflow integration guidance
- Solved Docker networking issues for container-to-container communication

Key improvements:
* Container-to-container API access for N8N workflows
* Automatic service dependency resolution (Ollama, Supabase)
* Comprehensive deployment options for different use cases
* Production-ready Docker network configuration
