Enable report_capacity_overflow=True in MoEMLP.call and propagate dropped_count and overflow_fraction through router_stats into the summarized training metrics logged to wandb. Per-layer and aggregate overflow metrics are now visible as train/router/dropped_count_total, train/router/overflow_fraction_mean, and per-layer variants.
