fix: alibaba provider default endpoint and model list (#3484)

- Change default inference_base_url from dashscope-intl Anthropic-compat
  endpoint to coding-intl OpenAI-compat /v1 endpoint. The old Anthropic
  endpoint 404'd when used with the OpenAI SDK (which appends
  /chat/completions to a /apps/anthropic base URL).

- Update curated model list: remove models unavailable on coding-intl
  (qwen3-max, qwen-plus-latest, qwen3.5-flash, qwen-vl-max), add
  third-party models available on the platform (glm-5, glm-4.7,
  kimi-k2.5, MiniMax-M2.5).

- URL-based api_mode auto-detection still works: overriding
  DASHSCOPE_BASE_URL to an /apps/anthropic endpoint automatically
  switches to anthropic_messages mode.

- Update provider description and env var descriptions to reflect the
  coding-intl multi-provider platform.

- Update tests to match new default URL and test the anthropic override
  path instead.
