Expose universal-blocking toggle in CTB toolbar popup

The CTB toolbar button (right-click) opens the focus-follows-mouse/
focus-follows-click dialog. Add the universal IMGUI click-through
blocking toggle there too so users can flip it without opening the
stock settings panel.

Extend the existing "Focus change is global" option to also save
and restore universalClickBlocking via Global.cfg. SaveGlobalDefault
now takes both flags and writes both keys; a new
GetGlobalDefaultUniversal mirror reads it back. RegisterToolbar's
OnGameSettingsWritten / OnGameNewStart / OnGameStateCreated propagate
both flags. Popup height bumped 350→400 to fit the extra toggle.
