Enhance Docker deployment with environment variable configuration

- Added environment variable setup in docker-compose.yml for VITE_API_URL.
- Introduced update-docker-env.sh script to create/update .env file for local and remote deployments.
- Updated Dockerfile to dynamically create env-config.js during build.
- Modified frontend to load environment configuration from env-config.js.
- Refactored API client to use centralized config for API URL.
