fix: add recording-name api key endpoint; appauth url fix

[jennifer-richards]

The main fix here is to register the /api/meeting/session/recording-name endpoint as valid for PersonalApiKey endpoints.

Along the way, found that tests were not validating the PersonalApiKey instances they were generating, so this updates the PersonalApiKeyFactory to do that validation and replaces calls to PersonalApiKey.objects.create() with the factory.

This conversion revealed a minor bug in the URL pattern for /api/appauth/ which is also fixed.
