Add Gitea self-hosted git/CI/registry to replace GitHub

Deploy Gitea via Helm with dedicated CloudNativePG database, in-cluster Actions runner (DinD), and built-in container registry. ArgoCD repoURLs updated to use in-cluster Gitea SSH. Preview ApplicationSet switched from GitHub PR generator to Gitea PR generator. App images now pull from gitea.coreworlds.io registry. Remaining setup after deploy: seal runner token, ArgoCD API token, and registry pull secret once Gitea is running. Add ArgoCD deploy key to Gitea repo settings.
