Updated Voice Agents

Voice agents are now created automatically when an assistant is set up. This happens in the background and does not affect assistant creation speed. For existing assistants that don't yet have a voice agent, the manual creation button remains available.
Any user can test a voice agent before purchasing a subscription. The agent is created immediately but without a virtual phone number. The number is assigned after clicking "Publish" — provided an active voice agent subscription is in place.
The TTS/STT models and the core LLM powering voice agents have been upgraded — quality is significantly better. Over 70 languages are supported: the agent detects the client's language automatically and responds in it. Allowed languages can be configured in the "Communication Languages" section.
Audio tags have been added to control how the agent speaks. The tag name describes the speaking style, and the description defines when that voice style should be used. New tags can be added manually.
