UK CONNECT PHASE 6 - LIVE ADMIN ENGINE

This is a separate cloned upgrade from Phase 5. Phase 5 is untouched.

Open this first:
  phase6-command-centre.html

What is new:
- Live Product Manager using browser localStorage
- Add/edit/delete/publish products
- Upload product image for demo use
- Live Shop Preview updates from Product Manager
- Basket/checkout enquiry demo
- Backend/database starter files for real deployment

Important:
This version works locally as a demo without a server. Product changes are stored in your browser only.
For the real live website, connect the same fields to a database, admin login and Stripe Checkout.

Suggested next build:
- Node/Express or PHP backend
- MySQL/Postgres database
- Stripe Checkout session creation
- Secure admin login
- Image upload storage
