feat: Ansible Playbook 全栈 CRUD + 真实执行 — 替换mock为后端持久化

后端:
- models/automation.go: Playbook 模型新增 Category/Tags 字段; 新增 CreatePlaybookRequest
- handlers/automation.go: 新增 runPlaybookLocal(写临时YML+ansible-playbook --connection=local执行)
  + randomCode(crypto/rand生成唯一code) + List/Get/Create/Update/Delete/Execute Playbook 完整CRUD
  Execute 创建TaskExecution(task_type=playbook)记录,采集stdout/stderr/退出码/耗时
- routes/routes.go: 注册 /playbooks 路由组(7个端点)

前端:
- services/api.ts: ansibleApi 从mock改为真实 /playbooks 后端调用
- AnsibleManager.tsx 完全重写:
  - Playbook管理: 真实数据卡片列表(id/name/category/tags/run_count/timeout) + 搜索/分类筛选
  - 新建/编辑对话框复用(编辑模式预填数据) — 新增编辑入口(原无编辑功能)
  - 查看内容: 终端风格YAML查看器 + 快捷编辑按钮
  - 执行: ConfirmProvider确认 + ansible-playbook本地执行 + toast结果反馈
  - 执行记录tab: 真实TaskExecution记录(任务名/状态/开始时间/耗时/日志查看)
  - 统计卡片: 总数/执行中/今日成功/今日失败(基于真实执行记录)
  - 移除原inventory占位tab(无后端支持,避免非功能按钮)
  - tags JSON数组与前端string[]互转映射
