feat: add nx-based test script to mimic ci

This commit introduces a new testing setup that mimics the CI environment. It uses nx to run tests for npm-app, backend, and common, ensuring a consistent testing workflow.

- Adds project.json files for backend and common packages.
- Updates npm-app/project.json with a test target.
- Modifies the root package.json to include a new test script that streams output and skips the cache.
