feat(test): B5 整合測試框架 — 真實 DB, 5/5 通過

新增:
- docker-compose.test.yml: CI 用臨時 pgvector PostgreSQL (port 15432)
- tests/factories.py: Incident/Approval/Knowledge/RAG 測試資料工廠
- tests/integration/test_b5_core_flows.py: 5 個 E2E 整合測試 (5/5 PASSED 1.03s)
- tests/integration/setup_test_schema.sql: CI schema 初始化 SQL
- cd.yaml: 新增 Integration Tests B5 step
- scripts/sync_dev_db.py: dev DB 同步工具

修正:
- .env.test: DATABASE_URL 指向 awoooi_dev (本機設定, gitignore 不入庫)

禁止 Mock 鐵律: 所有 DB 測試使用真實 PostgreSQL, 無 SQLite/MagicMock
