PipraPay/PipraPay ? reverse-engineered prompt

Build me a self hosted payment automation app called PipraPay that helps a business accept, verify, and track payments in one place.

It should support multiple payment methods through plugins, so I can add gateways and local payment providers without changing the core app. I want it to handle things like payment verification, SMS based confirmation, webhooks, and simple workflow automation after a payment comes in. Make it feel like a real admin portal where I can manage providers, see transactions, and connect everything through an API.

Please include a clean landing page, the main dashboard, basic setup and install screens, a maintenance page, and a 404 page. Keep the design modern and trustworthy, since this is for finance. It should be easy to deploy on my own server and ready for developers to extend later with custom integrations. If you need to check current docs or best practices for the stack, look them up online.
