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.
