Remove env_file from docker-compose and use explicit environment variables

- Remove env_file directive from docker-compose.yml to eliminate .env file dependency
- Add explicit environment variable declarations with default values using ${VAR:-default} syntax
- Update port mapping to use UNRAID_MCP_PORT environment variable for both host and container
- Include all 11 environment variables used by the application with proper defaults
- Update README.md Docker deployment instructions to use export commands instead of .env files
- Update manual Docker run command to use -e flags instead of --env-file

This makes Docker deployment self-contained and follows container best practices.

 The easiest way to run the Unraid MCP Server is with Docker:
 
 ```bash
-# Clone and configure
+# Clone repository
 git clone https://github.com/jmagar/unraid-mcp
 cd unraid-mcp
-cp .env.example .env

-# Edit .env with your Unraid API details
