build: Switch to esbuild

We will build all packages except the frontend (where vite remains in
use) with esbuild.

For some reason, the @yarnpkg/esbuild-plugin-pnp doesn't allow esbuild
to load esm modules and we fall back to commonjs for dependencies.
Hence we had to switch back to node_modules (but still rely on yarn
hardlinking for a more efficient install).
