subin20256/MERN-SeminarRegistration ? reverse-engineered prompt

Build me a full seminar registration app where people can sign up, verify their email with an OTP, log in, and fill out a registration form with their personal details and an uploaded image. After that, they should be able to pay for the seminar and then check the status of their application from their dashboard.

I also need an admin side where an organizer can log in, see all submitted registrations, review each one, and accept or reject applications. Users should be able to see whether they are pending, approved, or rejected.

Make it feel like a real modern web app, responsive on desktop and mobile, with a clean user dashboard and a separate admin dashboard. Store user data, registrations, and status in a database, handle file uploads properly, and wire up the payment flow so it can support common payment options. If you need current setup details for any library or service, look up the latest docs online and use sensible defaults.
