ci: 统一 k8s manifest 为 apps/*/k8s/all.yaml

- 三个 app 的 5 个独立 yaml 合成单文件 all.yaml，多 doc 内显式排序，apply 不再受目录字母序影响（这是 piano-sheet run #49 NotFound 的根因）
- simpleasm/cube workflow 补 Initialize K8s resources 步骤，跟 piano-sheet 对齐；今后 manifest 改动 CI 自动 apply
- cube 的 _registry-ingress.yaml 不再需要前缀绕排序，去掉 _

apps/piano-sheet/k8s/all.yaml
