WhatsApp Action in RulesEngine Has No Dispatch Implementation

[krishnasahoo11156]

The RulesEngine evaluates rules and can produce a sendWhatsApp action, but whatsapp.adapter.ts does not exist. The action logs a warning and does nothing.

Steps to Reproduce

1. Create a rule with action sendWhatsApp
2. Trigger an email that matches the rule
3. Check logs: “WhatsApp adapter not implemented”

Expected Behavior
User receives a WhatsApp message within 60 seconds.

Fix Required
• Implement backend/src/services/outputs/whatsapp.adapter.ts
• Integrate Twilio SDK
• Add WhatsApp credentials to Integration model
• Add connection UI to frontend Settings
