✨(backend) activate LiveKit webhook event notifications

Enable LiveKit webhook feature to notify backend when events occur in rooms.
Configure LiveKit to call our endpoint whenever events are triggered,
providing real-time updates on room activities. Refer to LiveKit
documentation or LiveKitWebhookEventType enum for complete list of available
events.

This commit is not functionnal, LiveKit fails verifying our backend's
certificate. It will be fixed in the upcoming commits.
