**test(web-service): add cloud storage integration tests and update package settings**

- **Cloud Storage Integration Testing**:
  - Added `cloud-storage.test.ts` to validate cloud storage configurations (AWS S3, Cloudflare R2, Google Cloud Storage) and local storage fallback behavior:
    - Includes tests for environment variable priority and configuration detection.
    - Ensures proper override with `FORCE_LOCAL_STORAGE` when specified.

- **Package Settings Updates**:
  - Introduced `web-service-package/package.json` with configurations for building, running, testing, and deployment:
    - Added NPM scripts for building (`npm run build`), development (`npm run dev`), and testing (`npm run test:cloud`).
    - Configured dependencies and devDependencies for web service functionality and cloud integration.

- **Purpose**:
  - This update ensures comprehensive cloud storage testing and provides structured project configurations for seamless development and deployment workflows.
