"""Rename the billboard `my-contacts` applet to `my-buddies` (slug + name).

User.buddies M2M (lyric/0004) lands at the same time; the applet links
to the new /billboard/my-buddies/ page where the user manages their
buddy list. "Contacts" was a placeholder name from the original
billboard scaffold.
