fix(gui): Correct indentation bug in _render_mma_dashboard that caused crash

The code after the 'prior session' return block was incorrectly indented
at 1 space, placing it inside the 'if is_viewing_prior_session' block
instead of after it. This caused 'total_cost' and 'perc' to be undefined
when viewing an active session, triggering an IM_ASSERT error.

Fix: Moved 'track_name', 'track_stats', and 'total_cost' to the
correct 2-space indentation (method body level).
