Add Playwright tests for live site authentication and race page loading

- Introduced `auth.setup.js` to handle authentication against the live site and store the session state.
- Created `live-race.spec.js` to test loading a live race page with an authenticated session, including cookie validation.
- Added utility functions in `live-site-test-utils.js` for managing authentication, dismissing cookie banners, and checking UI states.
- Included a temporary JSON file for live state inspection.
- Updated deployment manifest to reflect new and modified files.
- Implemented `_inc_faceai_identity.jsp` for managing FaceAI identity cookies and included it in relevant JSP files.
- Added language management JavaScript in `lang.js`.
- Adjusted `fotoCR-en.jsp` and `fotoCR.jsp` to include the FaceAI identity logic.
- Created a tarball for staging deployment.
