fix: pass user_id from .dspy to reasoning engine, remove hardcoded model

- reasoning_submit.dspy: pass user_id from await get_user() to hermes_reason_and_execute
- hermes_reason_and_execute: accept user_id parameter
- reason_and_execute: accept user_id parameter (removed ServerEnv.get_current_user fallback)
- _llm_call: remove hardcoded model=qwen3-max, let llm_chat use default_model from harnessed_agent_config
