feat(工作台): 三列表（账号/视频/AI写脚本）批量操作——左下角图标按钮+勾选批量删除

- 后端: dsh-data.js batchDelete(kind,ids)——accounts 软删(del_flag=1)+连坐清 persona/analysis/videos/source/analysis/rewrite_log; videos|rewrites 删视频行+关联(video_id 与 aweme_id 双键,兼容 video_id=null 历史行); server.js POST /api/dsh/batch-delete(kind 校验+空 ids 幂等)
- 前端: data-pages.js batchBarHtml/bindBatchBar + 三列表勾选列+左下角批量操作条; 图标版——app.js 新增 check-square/trash 图标, 批量模式图标右侧出 trash/x+全选+计数; style.css 批量样式+--danger
- 修复 P0: 账号连坐删除漏删 account_videos 行(孤儿残留), 已补并复验
- 验证: API 实测(删测试账号/视频连坐全清+非法kind+空ids) + CDP UI 33项PASS + 端到端删除 PASS(cdp-verify-batch.mjs / cdp-verify-batch-e2e.mjs)
