refactor(widgets): move WidgetStatus and WidgetPermissionReceiver to :widgets

Add bridge callbacks for updateSmallWidgetUi, updateAddNoteWidgets,
and isLegacyNotificationEnabled. Move allDecksCounts extension to
:widgets/utils. Remove remaining app-module dependencies from
WidgetStatus and WidgetPermissionReceiver.
