Tweak provider views (#1499)

* Add Organizations to provider views

Remove enabled/disabled toggle from provider. It's currently not used.

* Remove provider Delete

There are implications to deleting providers on the organizations they manage.
We want to think through this flow before allowing delete from the
admin portal.

* Use toastr to display production exception messages.

Update build actions to upgrade npm to v7.

Use a custom error handler in production which displays a toast of the
exception message and redirect to the offending page

* Clarify provider create error message
