  * WebRTCService - thin Angular service that composes specialised managers.

  * Each concern lives in its own file under `./`:
- *   • SignalingManager      - WebSocket lifecycle & reconnection
- *   • PeerConnectionManager - RTCPeerConnection, offers/answers, ICE, data channels
- *   • MediaManager          - mic voice, mute, deafen, bitrate
- *   • ScreenShareManager    - screen capture & mixed audio
- *   • WebRTCLogger          - debug / diagnostic logging

  * This file wires them together and exposes a public API that is
