Point the public pages at our own domain, and stop naming the admin account

Two fixes, both from Jörn's 2026-08-19 rule: keep the CV, Joanna's profile and
the Hoppe.home page current, and expose no secrets or internal infos.

1. The live pages had been hand-edited to use hoppe.mywire.org URLs, but that
   never came back to the repo, so Codebox Go still carried joernhoppe.github.io
   and donnyandjoern-debug.github.io in og:url, og:image, twitter:image and the
   "Meet Joanna" links. Codebox Go leads now, so the source says our domain.
   GitHub Pages stays as a mirror for links already handed out; a rel=canonical
   on every page means our domain is credited even when GitHub serves it.

2. Joanna's public profile published "joanna@hoppe.home - domain administrator"
   twice: the exact AD domain-admin account, the internal domain name, and
   confirmation of its privilege level, on a page linked from a public CV.
   That is half a credential pair plus a note saying what it unlocks. The
   governance point survives without it - she still reads as a first-class
   domain account by design rather than a shared credential.
