feat: 采集任务状态跟踪 ingest_jobs

新增 ingest_jobs 表(UUID/task/params/status/result/error/时间戳),
POST /ingest/bzzoiro 启动前插入 job(pending)→ 后台 running → success/failed,
响应新增 job_id(兼容原 message)。

Admin GET /admin/ingest/jobs/{id} 与 /admin/ingest/jobs?limit= 只读查询;
Collection 页提交后轮询 job 至终态,展示真实 result/error 汇总。
迁移 0019_ingest_jobs + 分批 get_uow/BzzoiroSource/IngestFailure 不变。

全量测试 270 通过。
