- Add deployment/ansible/templates/.env.production.j2 used by secrets playbook
- Enhance deploy-update.yml to read registry creds from vault or CI
- Update production-deploy workflow to pass registry credentials to Ansible
- Remove obsolete GitHub-style workflows under .gitea (conflicted naming)
Why: make the production pipeline executable end-to-end with Ansible and
consistent secrets handling; avoid legacy CI configs interfering.
