🔧 chore: Update next.config.mjs file

- Remove "productionBrowserSourceMaps" property
- Make "compress" property dependent on "isProd" variable
- Set "reactStrictMode" property to true
- Modify "images" property to set "unoptimized" based on "isProd" variable

These changes improve the configuration of the Next.js application.
