Kubernetes-dashboard: enhance Docker configuration and Next.js settings

- Updated `.dockerignore` to streamline build context by refining ignored files.
- Modified `Dockerfile` to set production environment variables and optimize the build process.
- Adjusted `next.config.js` to improve output tracing and enable SWC minification, along with experimental package import optimizations.
