Continue polling VariantStats while LLM retrieval in progress, minor UI fixes (#54)

* Prevent zoom in on iOS

* Expand function return code background to fill cell

* Keep OutputStats on far right of cells

* Continue polling prompt stats while cells are retrieving from LLM

* Add comment to _document.tsx

* Fix prettier
