fix: Fix build issues for release

[devongovett]

Two issues:

1. There were two files with the same name but different case being generated in the build (fonts.mjs due to css modules producing a JS file, and Fonts.mjs the component). Because macOS has a case-insensitive file system these overwrote each other. Renamed the CSS file to something else so that doesn't happen.
2. I thought Next.js would ignore the "use client" in S2 since it is not at the top, but it actually errors in that case. So we have to actually remove it from the build for now. Added a script to do that.
