Improve tracker source and first-party cleanup

Surface every CookieSource value in the console: the trackers page
filter was missing the HTTP option and the source badge helper had no
EXTENSION case, so HTTP-sourced rows could not be filtered and
extension-sourced rows rendered the raw enum string.

On the backend, the mark-first-party verdict now blanks the stale
description on both the catalog row and its uncategorised org tracker
patterns. A terminal non-third-party row keeps no vendor link, so a
description naming the (now-cleared) vendor would be misleading; the
mapping worker only copies descriptions into empty rows and never
clears them, so clearing is done explicitly here.
