fix(task-scheduler): Bug #10 — convention path fallback(visionA promote/result 拿不到 NEF)

visionA e2e 撞到:promote / result endpoint 在 status=COMPLETED 仍拿不到
NEF(409 source_not_available / 404 result_not_found)。

根因:worker (services/workers/consumer.py:118) 把 NEF/BIE/ONNX 上傳到
固定 convention path `jobs/{job_id}/out.{output_name}`、但 scheduler 端
advanceJob (jobService.js:246) 沒接收 worker done event 的 output path、
所以 job.output.{source}_path 永遠 null、讀取端拿不到。

修法 A(讀取端 fallback、最低風險):
- promote.js getJobOutputKey() + result.js extractNefObjectKey() 在
  status=COMPLETED + jobId 有效 + source ∈ {onnx,bie,nef} 時、反推
  convention path
- 不改 worker / 不改 advanceJob / 不改 redis schema
- fallback 放最後、保留 result_object_keys / output.{source}_path 兩種
  顯式設定優先級

Phase 2 backlog(待補完):
- 補完 worker → scheduler done event 寫 output path
- advanceJob 接收 output path 並寫進 redis
- 清掉本批 fallback dead branch + promote 409 source_not_available
  dead branch(fallback 後 valid source 永遠拿得到 key)

Tests: 666/666 pass(無回歸)
Reviewer:  通過、guard 嚴格、對齊 worker convention、無 path traversal 風險
