countly/countly-server — reverse-engineered prompt

I want a self hosted analytics and customer engagement platform like Countly that I can run locally and then deploy on my own server. Please put together the full app so it has a working dashboard and backend for tracking sessions, page views, events, crashes, and user activity across web, mobile, desktop, or anything sending data through an API.

It should feel privacy first, with user and app management, permissions, customizable dashboards, reports, alerts, webhooks, remote config, push notifications, in app ratings, and a plugin friendly setup so it can be extended later. I also want the read and write APIs working so other apps can send data in and pull analytics out.

Please make the easiest reliable local setup, Docker is fine if that is the smoothest path, and include sensible sample data or a demo flow so I can click around and see it working right away. If anything is unclear, check the current docs online and make practical choices for getting a solid working version running end to end.
