amanxthink11/quickqr ? reverse-engineered prompt

Build me a self hostable QR code platform for businesses with a clean dashboard and public QR pages. I want users to be able to create QR codes for things like links, UPI payments, WhatsApp chats, Wi Fi, vCards, maps, PDFs, phone numbers, SMS, and email, then customize the look with colors, logos, and print ready downloads.

It should also support dynamic QR codes with short links that can be changed later without reprinting, plus pause and archive states. Add simple analytics so people can see scan counts, device type, browser, location, and campaign tracking, but do it in a privacy friendly way without storing raw IP addresses.

Include embeddable website widget support, a developer API, login and organization based access, and a database backed setup that works well with PostgreSQL. If you need to check current docs for anything, look them up online.
