feat: aligner event handler Socket.IO sur le contrat snake_case (#20)

- Ecouter call_event au lieu de ipbx_event
- Lire event_code, queue_name, terminal en snake_case
- handleCallPickedUp/handleCallHungUp utilisent event.queue_name
- renderer.js lit data.queue_name
- 3 tests unitaires ajoutés dans socketio-adapter.test.js
