fix(phase3): Resolve remaining test failures and stabilize GUI

- Fixed
ullcontext NameError in gui_2.py.
- Corrected TestMMAApprovalIndicators to call real rendering methods on mock app.
- Updated 	est_history_manager.py to provide required context_files argument to UISnapshot.
- Stabilized 	est_z_negative_flows.py with robust polling for terminal response status and corrected field names.
- Cleaned up debug logging in 
ag_engine.py and pp_controller.py.
