Greptile Summary

This PR sets the lang attribute on bloom-link-grid elements to the collection's Language 1 tag, allowing CSS font rules in RAB books to target the correct script/language for book button labels.

• getLanguage1Tag() reads languageForNewTextBoxes from the runtime-injected GetSettings() and sets it on each link grid during initial setup (setupBookLinkGrids) and after the user confirms edits (editLinkGrid).
• The /// <reference path> directive is added so the existing collectionSettings.d.ts type definitions are available in this file.

Important Files Changed

Filename	Overview
src/BloomBrowserUI/bookEdit/js/linkGrid.ts	Adds lang attribute to bloom-link-grid elements using the collection's language1 tag, enabling CSS font rules to target the correct language; change is small, focused, and logically correct.

.bloom-canvas .bloom-canvas-element .bloom-link-grid .bloom-bookButton p {
    font-size: var(--DefaultBookButtonFontSize, 10pt);
    font-family: Andika, NotoSans, sans-serif;

What if their language needs a different font? It doesn't seem like any fixed list will do here.

I changed the code to inject the Language1 font on the paragraph elements.

The code has changed again to just set the lang attribute on the .bloom-link-grid elements.
