ci: Verifikations-Job nach GitLab portiert, Gitea-Workflows entfernt (CFGMON-11)

Der deploy-on-push-Check (YAML-Manifest-Pruefung, SOPS-ENC-Kontrolle) laeuft
jetzt als leichter Job in der Lab-GitLab-CI; milestone-release.yml war seit
jeher toter Code (kein Runner, Releases wurden manuell per API erstellt,
siehe Issue #33). Flux bleibt unberuehrt - es zieht weiterhin vom
Gitea-Mirror. Damit verliert der Gitea-Runner builder-1 seinen letzten
aktiven Konsumenten.
