Build me a simple web based system for a coin slot internet hotspot setup that works with a MikroTik router.

I want it to let a shop owner set up the device, connect it to the router, choose wireless or LAN mode, configure the SSID and coin slot settings, and manage promo rates and expiration times. It should have an admin login, a dashboard, sales reports, and a place to change custom PIN settings and anti abuse settings. The system should also be able to generate access codes without needing a separate device, and support multiple vending units.

Make the setup feel easy for a non technical user, with clear screens and default values that can be changed later. If it helps, you can look up current docs online for MikroTik or ESP32 stuff. Please also include the basic pages needed for the setup flow and a clean interface that works well on a small screen and in a browser.
