Synthflow TTS voice model

Synthflow TTS is now available as a voice model option in the agent editor. It delivers low-latency, natural-sounding speech across 32 languages with 12 built-in voices.

The GET /voices endpoint now supports search and provider query parameters for filtering, and voice responses include provider, gender, and languages fields.
