crazywriter1 523d8c38f9 fix: Alibaba/DashScope: preserve model dots (qwen3.5-plus) and fix 401 auth ...

When using Alibaba (DashScope) with an anthropic-compatible endpoint,
model names like qwen3.5-plus were being normalized to qwen3-5-plus.
Alibaba's API expects the dot. Added preserve_dots parameter to
normalize_model_name() and build_anthropic_kwargs().

Also fixed 401 auth: when provider is alibaba or base_url contains
dashscope/aliyuncs, use only the resolved API key (DASHSCOPE_API_KEY).
Never fall back to resolve_anthropic_token(), and skip Anthropic
credential refresh for DashScope endpoints.

Cherry-picked from PR #1748 by crazywriter1. Fixes #1739.
