Move remaining js1 build-* commands under the build namespace (#57348)

Summary:
Pull Request resolved: #57348

Follow-up to the `js1 build-cxx-api` rename. Move `build-geo-screenshot-tests`, `build-js-api`, and `build-twui-screenshot-tests` under the `build` group so they sit next to their siblings (`js1 build assets`, `js1 build turbomodule`, etc.) instead of being top-level hyphenated outliers.

Each old top-level command stays as a hidden alias that prints a deprecation notice and delegates to the new module, so existing muscle memory and any out-of-tree scripts keep working.

Also updates the two places that emit the old command names into user-visible output: the TWUI template comment headers, and the JS API snapshot failure message.
