[FR] Modernize #63
Description
The webapp was build on CRA (create-react-app), which is not being maintained anymore. So, towards building a monorepo for the whole cv-toolbox repos, we need a real overhaul.
Main idea steps are:
- Switch to pnpm & pnpm workspaces
- Switch to monorepo structure
- Siwtch to vite (rollup & esbuild)
- Switch to i18next
- Upgrade to Typescript 5.x
