Add tests for math rendering and interactive scenes; update navigation and viewport handling

- Updated `lab.spec.ts` to navigate directly to the field lesson.
- Created `math.spec.ts` with tests for math rendering, error checking, and responsive design.
- Added `test4.spec.ts` for interactive scenes, ensuring all questions are functional and accessible.
- Modified `vite.config.ts` to keep original question/answer links navigable in production.
