 """AI 功能入口的积分扣费装饰器 (#1895)

+2. **wrapper 绑定到被装饰模块的 globals**：Python 闭包的 __globals__ 默认指向定义闭包
+   的模块（即本文件），但 Pydantic 在解函数类型注解里的 ForwardRef 时（Python 3.12
+   eval_type_backport 路径）直接用 wrapper.__globals__ 查表，会找不到路由模块里

+3. **装饰器内部入口通过「本模块 __dict__ 动态查找」**：注入到被装饰模块 globals
+   的是一层薄的转发函数，每次调用都从 ``sys.modules[本模块]`` 里取最新引用，这样
+   测试里 ``monkeypatch.setattr(points_gate, "_points_gate_enabled", lambda: True)``
