fix(alicode-intl): use DashScope compatible-mode endpoint so standard keys work

Switch baseUrl from coding-intl.dashscope.aliyuncs.com (Coding Plan keys
only) to dashscope-intl.aliyuncs.com/compatible-mode so ordinary DashScope
API keys authenticate. Path /v1/chat/completions and preserveCacheControl
quirk unchanged.

Fixes #2591
