feat: Add Jenkins integration for testing with pre-push hook

- Configured Jenkins FreeStyle job to trigger on push
- Added `npm install` and `npm test` steps in Jenkins build configuration
- Updated pre-push hook script to trigger Jenkins job and wait for test results
- Installed jest, @testing-library/react, and @testing-library/jest-dom as dev dependencies for testing

This commit sets up automated testing in Jenkins before code is pushed to the remote repository, ensuring code quality and preventing broken builds.
