feat(call): integrate call handling and WebSocket support

- Added CallHandler and related services for managing call sessions and participants.
- Enhanced WSHandler to support call signaling, including invite, answer, reject, and end functionalities.
- Updated router to include call-related routes for history and ICE server retrieval.
- Introduced WebRTC configuration in the application settings for call management.
- Refactored wire generation to include CallService and CallRepository for improved dependency injection.
