Disable fullscreen video in OverlayPanels

Disable fullscreen video in OverlayPanels

This change hides the fullscreen button for videos in Reader Mode
and uses an empty implementation of ContentVideoViewEmbedder in case
it is somehow triggered. This is a temporary measure until a proper
fullscreen handler can be implemented.

This is to prevent crashes until we have a proper fullscreen video solution.
