Update Dockerfile to use Node.js 24 and enhance build process

- Changed the base image for the frontend builder to Node.js 24-slim for improved performance and compatibility.
- Added commands to copy Node.js and npm from the Node.js 24-slim image, ensuring the latest versions are used in the build environment.
- Created symbolic links for npm and npx to streamline package management commands.
