- The `scopes_form` partial can be used in the `admin/applications` view
as well
- Don't allow partials to access instance variables directly. Instead, pass
in the instance variables as local variables, and use `local_assigns.fetch`
to assert that the variables are passed in as expected.
- Change a few instances of `render :partial` to `render`
- Remove an instance of `required: false` in a view, since this is the default
- Inline many instances of a local variable (`ip = 'ip'`) in `auth_spec`
- Some views had a "Close" button. We've removed this, because we don't
want users accidentally hiding the validation errors and not knowing
what needs to be fixed.
- Some views used `li`, some used `p`, some used `span`. We've
standardized on `li`.
- Some views only showed the first error. We've standardized on showing
all of them.
- Some views added an `#error_explanation` div, which we've made
standard.
