Refactor Dockerfile and update Next.js configuration for improved build process

- Simplified the Dockerfile by consolidating dependency installation and streamlining the multi-stage build process.
- Changed the base image for the builder and runner stages to `node:22-slim` for better compatibility.
- Updated the Next.js configuration to remove the standalone output option and added a production start script in package.json.
