Previously, the production build never output sourcemaps. Now we emit one file for `index.js` because it is the most likely one where we need to be able to better debug reported issues like https://github.com/go-gitea/gitea/issues/27213. This will currently increase the binary size of gitea by around 700kB which is what the gzipped source map file has. Also, I fixed the CSS sourcemap generation which was broken since the introduction of lightningcss.
