[Feature]: Add support for secure access to Aliyun models in AgentScope

# Add support for secure access to Aliyun models in AgentScope

Our system needs to securely access Aliyun model services (e.g., Model Studio) using encryption protocols like TLS and token authentication. According to [Aliyun's documentation](https://help.aliyun.com/zh/model-studio/encrypted-access-to-model-inference?spm=a2c4g.11186623.help-menu-search-2400256.d_0), encrypted API calls are required for cloud model inference.

## Request

Does AgentScope currently support this secure access pattern? If not, would it be possible to implement a standardized solution for encrypted cloud service integration?

## Use case

Securely call Aliyun-hosted models while complying with enterprise security policies (e.g., TLS encryption, token-based authentication).
