Unify unread badge and archive X into single column on Mine tab

The unread dot and dismiss X now share the same rightmost column on
the Mine tab.  When an issue is unread the blue dot shows first;
clicking it marks the issue as read and reveals the X on hover for
archiving.  Read/unread state stays in sync across all inbox tabs.
Desktop dismiss animation polished with scale + slide.
