fix(critic-hotfix): 4 修補 critic BLOCKER + HIGH（CD 阻塞 + 飛輪空轉）

Critic 全面審查 6 個 commit 後抓出：

CD 阻塞修復:
- test_ai_router_failover_integration.py: 3 個 test 改用 patch.object 直接
  mock _select_provider_and_model 強制初始 OLLAMA。原 IntentType.UNKNOWN mock
  在 router 內仍被 reclassify 成 DIAGNOSE → openclaw_nemo，failover 不觸發。
  → 5/5 PASSED

BLOCKER B1 — Gitea Telegram 通知永遠發不出去:
- apps/api/src/api/v1/gitea_webhook.py:399
  redis = await get_redis()  →  redis = get_redis()
  原 await 會 raise TypeError 被外層 except 吞 → Task C PR merged + workflow_run
  failure 通知全部失效（CI 綠燈是假象，test 只驗 HTTP 202 不驗實際送達）

BLOCKER B2 — P1.3+P1.4 學習鏈閉環空轉（兩處同 bug）:
- apps/api/src/api/v1/webhooks.py:261
- apps/api/src/services/approval_execution.py:771（pre-existing）
  EvidenceSnapshot.get_latest_snapshot(...) 是 module-level async function
  不是 classmethod → AttributeError 被 except 吞成 warning
  → 飛輪閉環假性接通實際空跑（feature flag default off 暫時免爆）

HIGH H3 — main.py lifespan 順序競爭:
- apps/api/src/main.py: configure_alerter() 移到 _recovery_svc.start() 之前
  原順序：start() 觸發 immediate-check → 可能呼叫 alert_recovery，但 alerter
  尚未注入 Redis → dedup fail-open，重複告警風險。

HIGH H1 — Gemini quota dedup 跨日吞告警:
- apps/api/src/services/failover_alerter.py:89
  dedup key 加 :{YYYY-MM-DD} 後綴，每日獨立 dedup window
  原昨 22:00 觸發，今 21:30 再觸發時 dedup 還沒過期會被吞掉

Tests: 14 passed (failover_alerter + ai_router_failover_integration + lifespan_wiring)

延後 follow-up:
- H2: proactive_inspector memory metric 改名 + baseline 清理
- H4: probe_success NaN fallback
- M1-M4 / S1-S2: 見 critic 報告
