feat(flywheel): Phase 4 — KM conversion hook + daily vectorize cron

ADR-073 Phase 4-2: incident_service.resolve_incident() KM conversion hook
- resolve 時 fire-and-forget KMConversionService.convert(incident)
- 已解決的 Incident 自動轉換為結構化 KM 條目，完成飛輪「學習固化」節點
- KMConversionService (Phase 4-1) 已存在 (km_conversion_service.py, 336 lines)

ADR-073 Phase 4-3: 15-cronjob-km-vectorize.yaml
- 每日 03:00 台北時間呼叫 /api/v1/knowledge/embed-all
- 自動向量化當日新增 KM 條目，確保 RAG 查詢不遺漏新知識
- 加入 kustomization.yaml resources

Phase 4-4: handle_callback log_manual_fix 已存在 (telegram_gateway.py:2468)
