Show duration dialog when pressing new QS toggle

When turning on DND, if the user has the setting enabled to "Ask every
time", we should show the duration dialog when the new quick toggle in
the Modes tile is pressed. This matches the behavior of the old DND
tile.

Also added logging, and moved the code that creates the dialog to the
delegate to reduce code duplication.
