build: migrate to vite and update dependencies

Migrates the React app from Create React App (CRA) to Vite
for faster build times and improved development experience.
Also updates all dependencies to their latest versions.

BREAKING CHANGE: Removes react-scripts and CRA-related
dependencies.  The development and build processes now rely
on Vite.
