app: Refactor all apps to use the Info component
- Remove the need to pass all the individual information elements to the AppView
  separately. This eliminates many issues with elements that were mistakenly not
  sent to AppView. Also reduces a lot of code duplication.

- Create App classes for power and sso for consistency.
