Refactor plan models and update team selection logic

Replaces MPlan and MStep definitions in messages_kernel.py with a generic dictionary for m_plan, and moves their definitions to models.py. Updates plan_service.py to store m_plan as a dictionary using model_dump. Uncomments and enables in-memory team selection in router.py for current user.
