[bobbai00]

What changes were proposed in this PR?

This PR improves the single-node docker-compose configuration with the following changes:

1. Added microservices:

   • config-service (port 9094): Provides endpoints for configuration management
   • access-control-service (port 9096): Handles user permissions and access control
   • workflow-computing-unit-managing-service (port 8888): Provides endpoints for managing computing units
   • All services are added with proper health checks and dependencies on postgres
   • Nginx reverse proxy routes are configured for /api/config and /api/computing-unit

2. Removed outdated environment variables from .env:

   • USER_SYS_ENABLED=true
   • STORAGE_ICEBERG_CATALOG_TYPE=postgres

3. Removed unused example data loader: the example data will be loaded via other ways, not the container way anymore.
