When toggling video mid-call, addVideoTrack triggers
onRenegotiationNeeded but the callback was empty — the remote peer
never received the updated SDP, so video never appeared on their side.
This wires up the full renegotiation flow using the existing
CallRenegotiateEvent (kind 25055):
- WebRtcCallSession: forward onRenegotiationNeeded to a callback
- CallController: create and send renegotiation offers, handle
incoming renegotiation offers by creating answers
- CallManager: route CallRenegotiateEvent, allow CallAnswerEvent
during Connected state for renegotiation answers
