feat(tasks): 删除任务可选连带删除资产/漏洞/流量/文件(默认不选)

删除弹窗新增四个默认不勾的复选框:
- 删除关联的资产:仅删本任务独有资产,与其他任务共享的仅解除关联(保留)。
- 删除发现的漏洞:删本任务全部 findings。
- 删除测试的流量:按本任务资产的 host 清录制流量(host 无任务标签,会连带清
  其他任务命中同一 host 的流量)。
- 删除测试过程中写的文件:删 <workDir>/tasks/<id> 目录(worker 产物 + 上传)。

- db: AssetStore.DeleteByTaskID(独有删+共享解关联)/HostsByTask;DeleteFindingsByTask。
- server: pgDeleteTask 读可选 JSON body {assets,findings,traffic,files},先按 host
  清流量(需在删资产前取 host)→删漏洞→删资产→删任务→删文件目录;空 body=只删任务。
- web: api.deleteTask(id,opts);删除弹窗四复选框(默认不选)+说明。

go build/vet、tsc 通过;新增 TestDeleteByTaskID(独有删/共享解关联/host 反查)。
