Refactor deployment process to use prebuilt Docker images

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.
