Title: partial fix for #25247: default height of hairpin

Aligns hairpin vertical position with dynamics as per Gould p. 103. This works with current Dynamics text style. I suppose we could consider calculating the hairpin height from Dynamics style rather managing two separate style parameters, but someone is bound to prefer having separate control.
