Add Gitea Actions CI, ArgoCD Application, and Gitea Packages wiring

- .gitea/workflows/ci.yml: build → seo:lint → e2e → image build/push →
  bump k8s image tag and commit back (paths-ignore + [skip ci] guard)
- argocd/bcs-website-application.yaml: ArgoCD App (internal Gitea repoURL, k8s path)
- k8s: image → Gitea Packages path; kustomization images newTag stanza
- ADR-0007 (Gitea Actions + Packages), supersedes GHCR/GitHub bits of ADR-0001
- Reconcile gitops-deployment-strategy.md to Gitea
