feat(whatsapp): implement send_voice for native audio message delivery - #13002
Merged
Conversation
WhatsApp already receives incoming voice messages (audio/ogg via the bridge) but lacked a send_voice implementation, so TTS and audio responses fell back to the base class send_image path instead of being delivered as native audio messages. Route send_voice through the existing _send_media_to_bridge helper with media_type='audio', matching the pattern used by send_video and send_document.
