fix(alicode-intl): split into Coding Plan + Model Studio providers

8b9cac1 swapped alicode-intl to the DashScope compatible-mode endpoint to
fix #2591 for standard DashScope keys, but that broke Coding Plan keys
(sk-sp-...) which only work on coding-intl.dashscope.aliyuncs.com. The two
key types use two different hosts and are not interchangeable.

- alicode-intl: revert to coding-intl endpoint (Coding Plan keys)
- alims-intl: new provider for dashscope-intl/compatible-mode (standard keys)
