refactor(infra): gate Gitea and act-runner behind var.enable_gitea
All Gitea and runner resources use count = var.enable_gitea ? 1 : 0 (or for_each with an empty set when false). The gitea namespace is conditionally included. Default is false. To enable: terraform apply -var enable_gitea=true Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
