Remove Pydantic validation to test serialization

- Remove ChatCompletionResponse validation from GoogleProviderHandler
- Remove ChatCompletionResponse validation from AnthropicProviderHandler
- Return raw response dict directly
- Add logging to show response dict keys
- This tests if Pydantic validation was causing serialization issues

Testing if removing validation fixes client-side 'Cannot read properties
of undefined' errors.
