refactor(test): extract JavaScript test code to test-lib.js

- Created tests/test-lib.js with testBackgroundComputation() function
- Updated test_verify.py to load and execute test library via Marionette
- Modified Dockerfile to copy both test-lib.js and test_verify.py to /app/tests/
- Improved code organization and reusability
