feat(providers): add DaoXE OpenAI-compatible gateway

- litellm/llms/openai_like/providers.json: daoxe entry (base_url, env keys, param mappings, supported endpoints)
- litellm/types/utils.py: DAOXE in LlmProviders enum
- provider_endpoints_support.json: DaoXE row (chat_completions + responses), including the interactions flag
- tests/test_litellm/llms/openai_like/test_daoxe_provider.py: registry + endpoint tests
