Switch from `nginx:1.29-alpine-slim` to `nginxinc/nginx-unprivileged:stable-alpine` for improved security by running as a non-root user. Changed the exposed port from 80 to 8080 in the configurations to reflect the unprivileged setup. Adjusted the `docker-compose.yml` and `nginx.conf` accordingly.
Replaced local builds with prebuilt backend and frontend Docker images for simplified deployment. Updated documentation and Makefile to reflect the changes and added a bootstrap script for quick setup of deployment files. Removed deprecated `VITE_API_URL` variable and references to streamline the setup.
