fix(provider-form): prevent duplicate submissions on rapid button clicks (#1352)

Make ProviderForm.handleSubmit async and await onSubmit so react-hook-form's
isSubmitting state is tracked. Disable submit buttons in AddProviderDialog and
EditProviderDialog while submission is in flight via onSubmittingChange callback.
