tabs by default

[Szeraax]

Right now, devices don't exist until you have multiple tabs. This is to support the basic single tab functionality. We probably want to complete the tabs work and make it so by default every instance uses tabs and devicse. Will require migration work for local storage layouts and creating devices.

Also should change us from "if no tab specified, only show widget on tab 1" to "set default for widgets to be on tab 1 and migrate all widgets with no tab assignments to tab 1"
