Make naming of JS model files consistent.
Review Request #13156 — Created July 20, 2023 and submitted — Latest diff uploaded
For a long time we've had a mix of filenames for JS model files, with
some of them ending in "Model" and some of them not. This change makes
all of our new TypeScript code consistent, standardizing on the form
that includes "Model" in the filename. As more things are ported, we'll
fix up the remaining ES6/JS files.
Ran js-tests.
