[Feat]: Simplify the visualization of the war room list

[shyamvalsan]

Problem

With the introduction of the new "My rooms" "All rooms" buttons the interface is quite "busy" and a bit distracting (imo)

Also, as a user it is not very evident to me what "My rooms" means here? Is it a room I created (no), Is it a room I can view the metrics for (again, no).

Only on clicking "All rooms" and mouse overing the green tick icon and seeing the tooltip tells me this is related to notifications

The room I am not subscribed to notifications for has no icon at all - and hence no tooltip either. So I have to understand by negation that I won't receive notifications from this room.

This experience feels unnecessarily roundabout, especially for new users.

Description

If the intent of the newly introduced buttons is to show the user which rooms they are officially "part of" and subscribed to notifications for, then this could be shown in a more subtle way.

Similar to how red|yellow|grey icons are shown next to each room to indicate active alerts, we could show a crossed out notification icon next to rooms that a user is not subscribed to notifications for. A tooltip can explain this in text -- and clicking on this could take the user to the settings page where they can join and subscribe to notifications (if they have permissions to do this).

don't see many questions or complaints on this topic, so was wondering if we should keep this open

[shyamvalsan]

@hugovalente-pm this is the kind of thing that people may not complain about but it still hampers the experience, I think we should rethink it. Lets keep it open, and maybe we can brainstorm with @christophidesp about this.
