Title: Fix #18664

Edit Staff Types dlg box uses a separate copy of score styles
Edit Staff Types dlg box does not clear the type name when using presets
Edit Staff Types dlg box shows preview for TAB types
Score imports a list of staff types with a in-place deep copy (to keep valid pntrs to type in staves)
