D146: 修复qwen-vision.py密钥加载路径

- 变量名改为ALIYUN_QWEN_VL_KEY + ALIYUN_QWEN_VL_ENDPOINT
- 按LOCAL-SECRETS-PATH.hdlp顺序读: 本地secrets → .env → 环境变量
- 头部注释写明密钥来源路径规则

 用阿里百炼 qwen-vl 模型看图片，输出风格/色调/构图分析
 
+⚠️ 密钥不在代码仓库里。读取规则见 LOCAL-SECRETS-PATH.hdlp。

+  1. /Users/bingshuolingdianyuanhe/Documents/guanghulab-local-secrets/video-ai-system.env
