Notification Decoration Revised (#5312)

1. I removed the grey dots for when there is activity in rooms set to mentions or mute.
2. For all unread rooms, I made the message preview text bold for better legibility
3. For rooms with no unreads, I made the font weight regular, again for legibility

We have also mergeg the new room list activity rendering with the existing feature hide unread badge feature flag and provide 3 variations: current production behavior, no badge but bolding, and no bolding and no badge
