chore(conductor): Mark track 'Fix Concurrent MMA Live GUI Tests' as complete

Fixes UI flickering between tracks in app_controller.py and an indentation bug in multi_agent_conductor.py that caused workers to crash silently.

    *Link: [./tracks/fix_concurrent_mma_tests_20260507/](./tracks/fix_concurrent_mma_tests_20260507/)*
    *Goal: Fix timeout issues in concurrent MMA track execution tests (test_mma_concurrent_tracks_sim.py, test_mma_concurrent_tracks_stress_sim.py, test_visual_sim_mma_v2.py). Workers run correctly but tests timeout due to infrastructure issues.*
