Subject: [PATCH] feat: Optimize Docker image with standalone output

This commit optimizes the Docker image size by leveraging Next.js's standalone output feature.

Key changes:
- Enabled `output: 'standalone'` in `frontend/next.config.mjs`.
- Modified the `Dockerfile` to build a smaller production image:
  - Copies only the necessary artifacts from the frontend build (`.next/standalone`, `.next/static`, `public`).
  - Removes the need to copy the entire `node_modules` directory.
  - Updates the startup script to use `node server.js` to run the frontend server.

This significantly reduces the final image size, addressing the user's request for a smaller Docker image.
