chore: Update Docker configuration and documentation

### Summary of Changes
- Enhanced `docker-compose` files to include BuildKit compatibility settings for improved caching during builds.
- Updated service definitions to use pre-built images from the specified Docker registry, ensuring consistency across environments.
- Added Docker registry configuration to the `.env` example file for clarity on deployment settings.
- Revised the `README.md` to include instructions for using pre-built images and local development setups, along with Docker compatibility troubleshooting steps.
- Introduced health checks in the `Dockerfile` for the API Docs service to ensure container readiness.

### Expected Results
- Improved build performance and deployment clarity, facilitating easier setup for new developers and enhancing overall project maintainability.
