feat: switch outbound dial to Kookoo API — outbound calls now work

- Replace CloudAgent V3 tbManualDial with Kookoo outbound.php
- Simple HTTP GET with api_key — no auth issues
- Kookoo callback endpoint: POST /webhooks/kookoo/callback
  - Creates Call record in platform
  - Matches caller to Lead by phone
- Remove agent login requirement before dial
- Tested: call queued successfully, phone rang
