This sets us back up to use Vite via the electron-vite package. This
will let us continue to build our testing suite on Vitest and take
advantage of Vite features like Hot Module Reloading, etc.

This cleans up the unused/unnecessary css properties added around the
same time as the modal component. This mostly refers to variables that
started with --app. They have been removed and their uses have been
replaced with other defaults. The --warning-color and --success-color
properties still exist despite being unused since they seem to fit with
the --error-color which is already in use.
