feat: Ansible 15个运维模板 + 主机匹配 + 远程执行

**种子模板（15个）：**
- 系统信息收集、安全更新、磁盘清理、服务巡检
- 用户SSH管理、Nginx配置、SSL证书检查、配置备份
- 进程诊断、Docker清理、防火墙、时间同步
- 日志轮转、内核调优、网络诊断
- 分类覆盖：maintenance/security/configuration/backup/monitoring

**主机匹配 API：**
- GET /api/v1/ansible/match-hosts?pattern=&match_type=regex|prefix|contains
- 支持正则/前缀/模糊匹配 hostname, IP, tags
- 复杂正则回退到 Go 过滤
- 分页支持

**远程执行增强：**
- 指定 target_hosts 时自动查询 SSH 信息生成临时 inventory
- 未指定时回退到 --connection=local
- 自动禁用 StrictHostKeyChecking
