Vite migration

[dennisgsmith]

Using Vite allows:

• More extensible bundler config without ejecting CRA or using CRACO / react-app-rewired
• Faster HMR, better devx, etc.

Migration includes:

1. Move index.html to root and update configuration
2. All files that return jsx must have.jsx extension
   a. Find and replace bash script: find . -iname "*.js" -exec grep -q 'import React' {} \; -exec mv "{}" "{}x" \;
3. Add vite.config.js file
4. Update process.env with import.meta.env and process.env.NODE_ENV === 'development' | 'production' with import.meta.env.DEV | PROD respectively
5. Remove remaining CRA/webpack code
6. After Vite setup, eslint errors / warnings fixed

Issue encountered with Plotly.js due to upstream outdated d3 version. WIP

[dennisgsmith]

Issue ended up being an outdated Plotly.js dist, rather than the main dist. Note:

• global needed to be available and set to globalThis for d3 es6 compatibility (see vite.config.js)
• Instead of using cjs require, minify-plotly now uses mjs import * as Plotly from '...' syntax so it can export as ESM with proper default

Everything is now working as expected.
