feat: enable production source maps for easier debugging

Added productionBrowserSourceMaps: true to Next.js config to enable
source maps in production builds. This will make client-side errors
much easier to debug by showing the original TypeScript source files
and line numbers instead of minified JavaScript.

Trade-off: Slightly larger build artifacts, but worth it for the
improved debugging experience. Source maps are downloaded on-demand
only when DevTools are open.
