Move notification button to UserInfo

Move notifications button to a more appropriate position next to username. It used to live in the room/spaces bar, which doesn't make sense context wise. Also the mobile view moves to a bottom navbar anyway.

This is just a copy-paste of the adjacent settings tool button with appropriate icon and callback.
