- WhatsAppService($canal): when 'turnero', swaps phoneNumberId to whatsapp_phone_number_id_turnero
so outgoing messages actually go from the turnero number (not the main bot)
- webhook.php: reads metadata.phone_number_id from the payload and compares it to
whatsapp_phone_number_id_turnero; if it matches, saves canal='turnero' and skips bot processing
- Previously all incoming messages had canal=NULL/bot so Chat Turnero never saw them,
and all outgoing messages from Chat Turnero were sent via the wrong (main bot) number

- conversations.message_id ahora tiene UNIQUE index (aplicado en BD prod)
- saveMessage() usa INSERT IGNORE: si el mismo wamid llega dos veces en
paralelo solo una llamada procesa el mensaje y llama al bot
- La segunda llamada recibe rowCount=0 y hace continue sin pasar al bot
- Elimina race condition que enviaba bienvenida + términos simultáneamente
