Integrate Payment Gateway

I propose adding a payment gateway integration using Razorpay to the project.
This will allow users to make secure payments via UPI, credit/debit cards, and net banking directly within the platform.
The feature can be useful for subscription plans, premium features, or supporting the project financially.

The integration should:

Use Razorpay’s Checkout API for smooth user experience.

Ensure secure transaction handling and PCI-DSS compliance.

Provide a simple and user-friendly payment interface.

If this feature is approved, I’d like to work on it
