Enhance Jenkinsfile for frontend testing and update Playwright configuration

- Added a new 'E2E (docker compose + Playwright)' stage in the Jenkinsfile to run end-to-end tests using Docker Compose and Playwright.
- Updated the 'Test frontend' stage to utilize the Playwright test image and improved error handling for missing files.
- Modified Playwright configuration to use an environment variable for the base URL, enhancing flexibility in CI environments.
- Expanded TypeScript configuration to include additional test and configuration files for better type checking.
