Turnero messages were triggering the SSE event that conversations.php listens to,
causing the contact to flash briefly at the top of the list before disappearing
on the next poll (since get_conversations.php filters them out by canal).

- 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
