GetLocation as Point.WithMonitor to ensure correct monitor association

Previously, dialog positioning could be incorrect if the monitor was
misidentified when restoring location. By returning the shell's location
as a Point.WithMonitor (including monitor reference), we ensure dialogs
and secondary shells open on the intended monitor, even in multi-monitor
setups. This fixes issues where dialogs could appear on the wrong
monitor after moving the parent shell.
