fix(tool-input): increase gap between SubBlock params for visual clarity

SubBlock's internal gap (10px between label and input) matched the
between-parameter gap (10px), making them indistinguishable. Increase
the between-parameter gap to 14px so consecutive parameters are
visually distinct, matching the separation seen in ParameterWithLabel.
