Place a voice call

Place a Telegram 1:1 voice call from the account that owns this private chat. Always ask the user to confirm before dialing. The audio plays in a browser tab the user keeps ready (none → audio_endpoint_required); the agent never hears or speaks. One call per account at a time; people who said STOP cannot be called; Safe accounts at most 10 calls a day, at least 60 s apart. Returns callId — follow it with calls.get or the call.* events.
