"""
准备分段 base64 payload,让 jumpserver 终端拼装并写入 /tmp/xxx.py

策略:
1. 在本机把 2 个 .py 转 base64
2. 按 N=400 字符一段切分(终端粘贴安全长度)
3. 生成一段 shell 脚本,内容是:
   cat > /tmp/auth_qrcode.py.b64 << 'B64_EOF'
   段1
   段2
   ...
   B64_EOF
   base64 -d /tmp/auth_qrcode.py.b64 > /tmp/auth_qrcode.py
   (同理 qrcode_service.py)
4. 把这个脚本写到 webcli_output 目录,用 jumpserver 终端 cat 出来
