Replace the manual WebRTC signaling implementation with LiveKit SFU. This includes: - Adding LiveKit service, handler, and configuration. - Updating Docker Compose to include LiveKit server, Redis, and PostgreSQL. - Refactoring `CallService` and `WSHandler` to support LiveKit room readiness instead of raw SDP/ICE relaying. - Adding new API endpoints for LiveKit token generation and webhooks. - Removing deprecated WebRTC configuration and manual signaling DTOs.
