OG T 716b94f60a feat(api): Phase 16 R4.2 抽取 ApprovalExecutionService
Strangler Fig Pattern: 從 approvals.py 抽取執行編排邏輯

新增:
- src/services/approval_execution.py (271 行)
- ApprovalExecutionService class
- 整合 OperationParser + Executor + Timeline + Notifications

瘦身成果:
- approvals.py: 1097 → 787 行 (-310 行)
- R4 總計: 移除 310 行內嵌業務邏輯

CI/CD 修復:
- 移除危險的 rm -f ~/actions-runner-* 指令
- 改用 checkout clean: true + workspace 內清理

Approval Execution Service - Phase 16 R4.2 瘦身 Router 抽取
============================================================
從 approvals.py 抽取執行編排邏輯,整合:
- OperationParser: 解析操作類型
- K8s Executor: 執行 K8s 操作
- ApprovalDBService: 更新狀態
- TimelineService: 記錄事件
- NotificationManager: 發送通知
版本: v1.0
建立: 2026-03-25 (台北時區)
