fix(graph): backfill 讀 entity 不帶 owner 過濾(存量 owner=None,濾了讀0);owner 只套建立的 gloss entry

合併 arcrun-7-gloss-bridge（A1 gloss 橋）與 owner-threading（owner_id 寫入鏈必經）：
- node-persist / triplet-ingest 衝突解為「兩者都要」：persistNodes 既寫 entity
  record（帶真 owner）又 upsert gloss entry（帶真 owner、帶 source）；ingestEnvelope
  既帶 source.uri 又 thread 必填 owner 到底。
- gloss 路徑補 owner 必填（配合 owner-mandatory D28）：
  * upsertGlossEntry(..., owner_id: string) owner 改必填
  * backfillGlossEntries(client, owner_id: string) owner 改必填
  * POST /backfill-gloss-entries 缺 owner_id → 400（存量 record owner=None，
    owner 由 caller 明確指定，不從 record 帶）
- 合併兩支測試：gloss 測試補 owner 參數以配合 base owner-required mock。

tsc：除 index.ts:57 swaggerUI 既存 baseline 外 0 error。
vitest：34 passed（gloss 7 + owner/graph 27）。
