The compliance-portal scaffold had an index.html pointing at a
src/main.tsx that did not exist, and carried stale config copied
from another app, so the bundle could not build.
Add the React entrypoint (main.tsx, App.tsx), a Tailwind index.css
wired to the standalone v2 theme, and vite-env.d.ts for the CSS
side-effect import and env typing. Scope the Tailwind @source scan
to packages/ui/src/v2 since this is a v2-only build, and use v2
color and type scales in index.html and App.
Drop the deprecated baseUrl from tsconfig.app.json and remove the
invalid react() babel relay option, which is unsupported by
@vitejs/plugin-react 6 and unneeded until Relay queries exist.
