fix(anki): hold playback paused while media timing review is open

- Defer overlay resume requests (popup closed, hover left) during an active review and apply them when the review closes
- Add deferPlaybackResume to the media timing review runtime and gate sendRendererMpvCommand on it
- Document the paused-playback behavior and add a changelog fragment
