feat: enable SSE streaming support in Anthropic handler

- Updated AnthropicHandler to check for streaming configuration before handling SSE transform.
- Modified handleStreaming to use the original request body instead of forcing stream to true.
- Adjusted the transformation logic in AnthropicToBifrost to respect the original stream setting.
- Added logging for SSE streaming configuration in the main application.
