fix(alibaba): use standard DashScope international endpoint (#4133)

* fix(alibaba): use standard DashScope international endpoint

The Alibaba Cloud provider was hardcoded to the coding-intl endpoint
(https://coding-intl.dashscope.aliyuncs.com/v1) which only accepts
Alibaba Coding Plan API keys.

Standard DashScope API keys fail with invalid_api_key error against
this endpoint. Changed to the international compatible-mode endpoint
(https://dashscope-intl.aliyuncs.com/compatible-mode/v1) which works
with standard DashScope keys.

Users with Coding Plan keys or China-region keys can still override
via DASHSCOPE_BASE_URL or config.yaml base_url.

Fixes #3912

* fix: update test to match new DashScope default endpoint
