fix(sandbox): fall back to config.configurable for thread_id in lazy sandbox init (#1529) 

* fix(sandbox): fall back to config.configurable for thread_id in lazy sandbox init

LangGraph Server injects thread_id via config["configurable"]["thread_id"],
not always via context["thread_id"]. Without the fallback, lazy sandbox
acquisition fails when context is empty.

* fix(sandbox): align configurable fallback style with task_tool.py
