fix #24349: fret offset text size as style
fix #24349: fret offset text left/right, as style
fix #24494: distance staff to fretboard diagram
minor fixes to the previous 2 commits

minor, as it works without those, but seems cleaner with:
ST_fretNumPos is int -> styleI() rather than stylD()
ST_staffFretDist gets multiplied by _spatium -> styleP() does this for
us, styleD() does not.
UI improvements
making fretboard distcance to staff consistent

with other similar settings by using negative values if above staff
