List voice languages

Return every language the agent can speak. The console UI shows them as the language picker.

The call returns all rows from the shared languages list. The selected languageCode values go into tts.supportedLanguages when you save the agent, and into the language filter on Browse the voice library. Nothing is stored.

Auth: Bearer token of a signed-in user, checked with the identity service. Rate limit: not documented. Processing: synchronous, one database read.
