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

+        For integration with N8N workflows or other containerized services:
+
+        ```bash
+        # Deploy to existing Docker network (e.g., localai)
+        docker-compose -f docker-compose.api-localai.yml up -d
+
+        # Find the container IP address
+        docker inspect mem0-api-localai --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}'
+        ```
+
+        **Usage in N8N HTTP Request Node:**
+        - **URL**: `http://172.21.0.17:8080/v1/memories` (use actual container IP)
+        - **Method**: POST
+        - **Headers**: `Authorization: Bearer mem0_dev_key_123456789`
+        - **Body**: JSON object with `messages`, `user_id`, and `metadata`
+
+        <Note>
+        **Perfect for Docker ecosystems!** Automatically handles Ollama and Supabase connections within the same network. Use container IP addresses for reliable service-to-service communication.
