feat: 定时任务关联脚本库 + 脚本库精简为shell/python

定时任务:
- 执行类型改为 Shell脚本/Python脚本/自定义命令 三选一
- Shell/Python 类型下拉关联脚本库, 选择后预览脚本内容
- 卡片显示关联脚本名 (Preload Script 已就绪)
- 去掉 playbook 类型

脚本库:
- 去掉 powershell/yaml, 只保留 shell + python
- 后端 validation 同步 oneof=shell python

涉及文件:
- script-helpers.tsx: scriptTypes 去掉 powershell/yaml
- CronJobFormDialog.tsx: 完整重写, 脚本库下拉+预览
- CronJobManager.tsx: type 标签对齐, 脚本名展示
- automation.go: CronJob type oneof 改 shell/python/command
                Script type oneof 改 shell/python
