Unify GUI scroll rates (#15902)

Use DPI-aware 20 DIP vertical scrolling for general-purpose GUI
scroll areas.

Keep list-based views aligned to their item height so one wheel increment follows the visible row rhythm.

This makes Preferences and other dialogs scroll consistently across
Windows DPI settings.
