docs: document pipeline fix v4 using buildkitd mirror and update workflow

Added a session log detailing the replacement of `iptables` DNAT with a rootless `buildkitd` mirror for internal Gitea registry access, eliminating the need for sudo, additional packages, or kernel-level configurations. Updated `.gitea/workflows/docker-publish.yaml` to reflect the new, purely configurational solution.

+      #          Login erfolgt ebenfalls intern (HTTP) → kein Pangolin-Timeout möglich.
