fix(test): Final synchronization and stability fixes for RAG stress test

- Improved AppController.ai_status to prevent overwriting 'sending...' with 'models loaded'.
- Enhanced 	est_rag_phase4_stress.py with robust polling and increased timeout.
- Synchronized App and AppController history objects to ensure consistent view.
