Consistent look and placement of "add" buttons, Add Device Dialog improved wording.

[Steve-Mcl]

Description

• Improve consistency across the "Add/Register" buttons. Now all buttons are adjacent to search
  • Add device
  • Add token (provisioning)
  • Add Application
• Ensure consistency across the "Add Device" dialogs
  • Improve readability (correct sentence order following addition of provisioning)

NOTE

• This is additional to the refactoring done in Application Instances: Team Devices #1809
• This is (re)based off the fix-1801-team-devices branch that Application Instances: Team Devices #1809 is on.

We have no concept of a device being added to an Application but not to an instance. A device is either added to a Team (unassigned) or added to a Team and assigned to an Instance. So I think the dialog text should reflect that - it doesn't need all three states.

Currently, when opened from the Application view, it assigns the device straight to the one instance in the Application. Once we support multiple instances, the dialog will need to include a list of instances to pick from when opened from the Application view... but that's a next-week thing.

Sorry guys, I am not up to speed on the whole application/ instance concept & so I only rejigged what was present in the code for layout continuity. Could I pester you two this morning for 5m (huddle) to get a handle on the concept so I can finish this up please?
