fix: complete streaming fix for all LLM providers and improve console handling

- Fix custom LLM streaming (Gemini/Vertex AI) in llm.py by removing verbose condition
- Improve console parameter consistency when streaming is enabled
- Ensures streaming works for stream=True regardless of verbose setting
- Maintains full backward compatibility
