FIX: Many bugs with admin badges interface

* Editing a badge's title would show it as changed in the side even if
  you didn't hit save

* Clicking a badge would not scroll to the top

* If there was an error saving a badge there was a missing i18n key

* URLs were using queryParams instead of paths

* User `label` tags for checkboxes for larger click targets

* Saved! text would persist when viewing another badge

* After creating a new badge it would show nothing

* Validation errors were not being properly released to the client

* Query errors were surrounded by an extra array
