chore: add tests

[nazarli-shabnam]

closes #18
This pull request introduces comprehensive test automation for both the UI and Python backend, adds initial test suites, and sets up the required configuration and dependencies to support these workflows. The changes ensure that both the frontend and backend are tested as part of the continuous integration (CI) process, increasing code reliability and maintainability.

CI/CD Workflow Enhancements:

• The GitHub Actions CI workflow (.github/workflows/ci.yml) is updated to run UI and Python tests automatically. This includes adding steps to install test dependencies and execute tests for both the UI (npm run test using Vitest) and Python backend (pytest). [1] [2] [3]

UI Testing Infrastructure:

• Adds Vitest and Testing Library setup for the UI:
  • Adds vitest, @testing-library/react, @testing-library/jest-dom, and related dependencies to apps/ui/package.json. [1] [2]
  • Adds vitest.config.ts and vitest.setup.ts for test configuration and environment setup. [1] [2]
  • Updates tsconfig.json to include test files and module resolution for new dependencies.

Python Testing Infrastructure:

• Adds pytest as a test dependency (requirements-test.txt) and configures test discovery via pytest.ini. [1] [2]

Initial Test Suites:

• Adds example test files for both backend and frontend:
  • Python: API health check (tests/api/test_health.py) and worker job processing tests (tests/worker/test_process_job.py). [1] [2]
  • UI: Component and utility function tests (tests/ui/components/page-header.test.tsx, tests/ui/lib/utils.test.ts). [1] [2]

Minor Code Quality Improvements:

• Refactors import usage in eslint.config.mjs for consistency.

Pull request overview

Adds automated test infrastructure for the UI (Vitest + Testing Library) and Python backend (pytest), and wires both into the GitHub Actions CI pipeline to ensure tests run on every push/PR.

Changes:

• Add initial UI unit/component tests and configure Vitest to run tests located under tests/ui/.
• Add initial Python API/worker tests plus pytest.ini to standardize discovery and import paths.
• Update CI workflow to run UI tests and Python tests before builds/compile checks.
