feat(remote-exec): 新增远程执行页(执行/上传) + 移除ansible命名 + 主机监控bug修复

远程执行页 RemoteExecPage：关联主机多选 + 批量执行命令 + 批量上传文件(Go-native SSH)，高危操作 useConfirm 确认；后端新增 multipart /remote-exec/upload-file 接口（接收文件→SCP 转发到多台主机）。

移除 ansible 命名：菜单 /ansible→/remote、组 id automation→task、子项 id ansible→remote-exec、种子显示名 Ansible→远程执行；删除 dead code ansibleApi。

主机监控 bug：installOne 不再强制 server.Status==running（默认 stopped 导致批量安装必失败）；UninstallAgent 凭据判断修正（SSH key 主机 Password 为空不应误判为无凭据而跳过远程卸载）。
