fix: Resolve CI/CD build failures by adding missing configurations

- Add missing tsconfig.json for encryption-service to enable TypeScript compilation
- Create Dockerfile for storage-hal (Rust service) to enable container builds
- Create Dockerfile for ml-optimizer (Python service) to enable container builds
- Create Dockerfile for sync-coordinator (Node.js service) to enable container builds
- Update microservices workflow to include encryption-service in Docker build matrix

These changes fix the CI/CD pipeline failures caused by missing build configurations
and Dockerfiles that prevented successful builds and deployments.
