Fix: compute __dirname in vite.config.ts (undefined under ESM)

Browse Source 
`__dirname` is undefined in ESM modules, so `path.resolve(__dirname, "./src")`
silently produced a bad path in Docker. Locally it happened to work (some
Node interop), but the Docker stage hit a clear error: "Could not load
/web/src/lib/utils ... ENOENT". Use fileURLToPath(import.meta.url).
