me-web? skeleton: Avalonia 12 app, server, packaging and CI

The first screen (online or not, a Check button, every language with a
draft notice), the desktop and Android heads, the server's /api/info and
/api/ip, a release tool that builds deb, rpm, a Windows exe, macOS zips,
a signed APK and the server, and the Gitea workflows that run it. Rules
adapted from passolo; AGPL-3.0.
