Prior to this commits note's kanban inner components were not aligned
properly. Moreover followers' avatars and the activity widget button
position were not visually consistent with the rest of the UI.
This commit fixes the design and limits the maximum number of rendered
avatars, adding a "+ [number]" label when the followers number
crosses the threshold of 5 entries.
