feat(mail-overview): split notification heading and use theme icon

The user's dunst format renders %a bold on the top line and %s
italic below it, so the app name now carries "New Mail" and the
summary carries "<account> (<count>)". mail-unread is not in the
active icon theme; mail-unread-multiple is.
