Private Connected Field Options Require Private Field Access

Form questions connected to a private custom field no longer return that custom field's current options unless the API key is allowed to access private fields. This affects jobPosting.info, feedbackFormDefinition.list, feedbackFormDefinition.info, surveyFormDefinition.list, surveyFormDefinition.info and interviewBriefing.info. Previously these endpoints returned the connected field's options regardless of the key's private-field access.
A key without private-field access receives the question's own configured options instead. For most forms that is a snapshot captured when the question was connected, so it may be stale rather than empty — it can omit options added to the custom field since, and can include options that are no longer valid.
Because of that, a key without private-field access can no longer reliably determine the valid values for such a question. Values submitted through applicationFeedback.submit are still validated against the custom field's real options, so a value taken from the returned snapshot may be rejected. Grant the key private-field access if it needs to read or write these questions.
