Jest 30 default test discovery was finding frontend/src/**/*.test.js
and __tests__/ files when running from the project root. These need
react-scripts (CRA's Babel config) to parse ESM imports and JSX.
Added jest.roots to confine root-level Jest to backend tests only.
Frontend tests run separately via react-scripts test in test-frontend.
