fix(ingest): 入库失败去静默化——真实原因落 error_msg

- _fail(): status=failed + error_msg 落库 + exception() 记日志（旧版只写
  metadata 且 UPDATE 自身异常被吞 → 文档永停 pending 无从排障）
- dbname 钩子缺失时兜底落错（脱离服务进程的裸任务不再无日志消失）
- 文本主路径：embedding 返回空 / VDB upsert 非 SUCCEEDED 直接 failed+原因，
  不再 except:pass 留 vector_id 空壳 done
- chunks INSERT 后补 COMMIT（纯 SELECT 后不 COMMIT 防 MDL 锁惯例）
