test: P2测试覆盖 — user/pool/schema_drift端点 43个新测试 (895→1017全通过)
新增测试文件: - test_user_endpoint.py (18 tests): 用户CRUD/列表过滤/权限控制/自删保护 - test_pool_endpoint.py (12 tests): 连接池状态/重置/概览/mock外部依赖 - test_schema_drift_endpoint.py (13 tests): Schema快照捕获/漂移检测/历史查询 覆盖率提升: - user端点: 0→18 tests (CRUD+权限+重复用户名+自删保护) - pool端点: 0→12 tests (stats/reset/overview+角色访问控制) - schema_drift端点: 0→13 tests (capture/check/history+dict序列化兼容) 修复: run.sh启动脚本同步
