front: migrate to vite

[multun]

This change switch from react-create-app to vite:

• 60 seconds for production builds
• 10 seconds for starting a development server¹

Close #3215

Use swc for dev builds

Swc is an faster alternative to babel. Babel is still used for production builds.
Please refer to the documentation of @vitejs/plugin-react-swc

Migrate to storybook 7 beta

Storybook 6 does not load vite.config.js. This is a huge issue,
as all vite configuration would have to be replicated into storybook.

Instead of writting hacks to backport this feature into storybook 6,
switch to the 7 beta, which loads and configures everything by itself.

Migrate tests to vitest

We cannot really use jest as it is tied to webpack.
Vitest is a drop-in replacement for jest, which works with vite.

I've added happy-dom as one of the tests starts up keycloak,
which breaks without dom access. Jest emulates the dom by default.
