重试队列增强 + 审计分页

- 后端: 添加 POST /api/retries/{id}/retry (手动重试) + DELETE /api/retries/{id}
  + 审计日志分页(offset/limit/count) + PushRetryJobRepo新增get_all/get_by_id/delete
- 前端retries: 手动重试按钮、删除按钮、状态过滤、操作人显示、toast反馈
- 前端audit: 分页控件(上一页/下一页)、每页50条、新增retry_job/delete_retry过滤
- 修复index.html: 适配审计API新返回格式(data.items)
