Add compatibility for Replit environment and local development

Update backend server to handle Webflow GraphQL endpoints and CSRF tokens, serve static files correctly, and use 0.0.0.0 host. Add a compatibility script for frontend Webflow e-commerce issues and update HTML files to include it.

+# Project Overview
+
+## Architecture
+- Static Webflow-exported frontend in the project root (`index.html`, `company.html`, `order.html`, `login.html`, `css/`, `js/`, `images/`).
+- Node.js/Express backend in `backend/` serves the root static site and `/api/*` endpoints.
+- Backend data is stored in JSON files under `backend/data/`; no external database is required for the current setup.
+
+## Replit Setup
+- Main workflow runs `cd backend && npm start` on port 5000.
+- Express listens on `0.0.0.0` and trusts the Replit proxy for preview compatibility.
+- Production deployment is configured to run the same backend server command.
+
+## Important Notes
+- Run backend commands from the `backend/` directory so static files resolve correctly.
+- The frontend API helper uses relative same-origin `/api` URLs when served over HTTP.
