Code Review Summary

✅ 变更逻辑清晰且正确。

变更分析：

1. bkflow/permission/models.py：新增 FLOW_VIEW/FLOW_EDIT/FLOW_MOCK 枚举值，将之前在 _inject_user_task_auth 中通过字符串拼接（f"FLOW_{permission_type}"）动态生成的权限类型显式定义为枚举成员，并添加到 TASK_PERMISSION_TYPE 中，确保超级用户/空间管理员获取到完整权限列表（包含模板派生权限）。

2. tests/interface/task/test_task_views.py：测试断言从硬编码字符串改为使用枚举值，保持一致性。

确认无问题：

• FLOW_* 权限是运行时合成的（view.py:171），不存储在 DB 中，因此 Token.PERMISSION_TYPE choices 无需更新
• TASK_PERMISSION_TYPE 仅在超级用户场景下使用（view.py:151），扩展不影响普通用户的权限查询逻辑
• 无安全、性能或架构问题

LGTM，无需修改。
