chore: Update environment configuration and Dockerfile for improved setup

- Change default PORT in .env.example to 7123 and update CORS origins
- Disable speech features in .env.example for a cleaner setup
- Modify Dockerfile to streamline Python dependency installation and improve build performance
- Add fix-env.js script to ensure NODE_ENV is set correctly before application starts
- Update smithery.yaml to include new Home Assistant connection parameters
- Introduce start.sh script to set NODE_ENV and start the application
