fix: anthropic adapter — max_tokens ignored, fallback crash, proxy base_url filtered

Browse source 
- Pass self.max_tokens to build_anthropic_kwargs instead of hardcoded None
- Add anthropic case to _try_activate_fallback (was only handling openai-codex)
- Remove 'anthropic in base_url' filter that blocked custom proxy URLs
