feat(phase6): 测试补全 + 集成测试 + repository 落地示范

- tests/unit/modules/test_repository.py：base_repository 在 SQLite 内存库的 CRUD 测试
- tests/integration/api/test_smoke.py：登录链路 / 只读接口 / 未授权拦截（标记 integration，默认跳过）
- conftest 提供 sqlite_db（隔离 DB）与 app/client/admin_headers（集成）fixture
- pytest.ini 默认跳过 integration，Makefile test-integration 可显式运行
- 修复 base_repository.get_by_id/get_by_ids 对字符串 ID 的兼容（URL 路径参数）
- 示范 modules/system/level service 改用 level_repo，CRUD 全链路实测通过
