Introduced a secure, repeatable production proxy profile for reverse proxy and HTTPS deployment, including NGINX configuration, environment variables, and CORS guidance. Added CI workflow for static validation of proxy guardrails and detailed documentation to ensure best practices in deployment.
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.
