ci(k8s): Gitea K8s pipeline ekle — CiroMarket K8s migration

Ne yaptık:
- .gitea/workflows/deploy-backend.yaml — Gitea Actions ile backend image'ı build et, Gitea registry'e push et, ci-cd repo manifest'ini bump'la
- .gitea/workflows/deploy-frontend.yaml — Frontend'i VITE_API_URL=https://trendyol-api.194.187.253.61.sslip.io ile build et, aynı pattern
- .github/workflows/deploy.yml — sync-gitea job eklendi: GitHub push sonrası Gitea mirror sync + deploy-backend/frontend.yaml dispatch

Neden yaptık:
- CiroMarket'i Coolify'dan K8s'e taşıma projesi
- Coolify pipeline parallel çalışmaya devam ediyor (zero downtime)
- GitHub push → Gitea mirror → Gitea Actions → Gitea registry → ArgoCD → K8s rolling update zinciri tamamlandı
