Normalization logic duplicated

Lines 541-544 inline the same three-pass label_replace normalization as the Model Comparison table and lines 585-587, so any regex tweak has to be updated in several places and can drift — should we factor it into a shared Grafana template/variable or reuse the existing expression?
