v1.2.1

Just some UI/UX improvements:
-Devices page: Layout is now consistent with Models settings where the settings are in a modal not directly on the page.
-Devices page: Device type now displays in all caps to match how device identifiers are displayed
-Packages page: Since Default package can not be renamed or deleted, the Delete button for that package is now not displayed, and the Name input field is now disabled. Before, attempting these actions would correctly result in an error, but the front end UI elements to attempt those changes were still present.
