EmberEmu/Ember ? reverse-engineered prompt

Build me this World of Warcraft 1.12 server emulator so I can get it running locally and see how it works.

I want a clean setup that I can start with Docker, plus simple instructions for getting the server, database, and config ready if I want to do it the manual way. Make sure it can compile on a modern machine, starts without a bunch of guesswork, and shows the retro banner when it launches. If anything in the docs is outdated, update it as you go, and if you need to check current setup details online, do that.

Please also make the default experience feel polished, with sensible configs, clear startup steps, and anything needed so someone can test logging in and connecting to the emulator without having to dig through the code.
