Refactor Docker configurations for frontend and Celery worker

- Updated the Celery worker command in docker-compose.yml to remove unnecessary flags for improved performance.
- Modified the frontend Dockerfile to use pnpm instead of corepack for package management and included pnpm-workspace.yaml in the build context.
- Adjusted the Dockerfile to correctly copy the nginx configuration from the build stage.
- Added network and build arguments for HTTP proxies in the docker-compose.yml for better network handling.
