test(modules): hold every surface list against the surface map

Each family of ids must name a surface that exists (nav hrefs, sub-page
directories, section ids, widget ids, derived ids, Settings slugs,
correlation channels). Sub-pages, trend slots and correlation channels
must follow the owner of the types they plot, joined against the
dashboard's summary owners, and a pinned table covers the owners no
join can derive. The replaced per-surface keys and the redirecting page
guard are searched for in source, and the derived route's gate is
compared with the map entry by entry.

Broken on purpose before committing: dropping the sleep sub-page entry,
the mood trend entry or a nav entry, drifting a derived owner, and
reintroducing a per-destination key each fail by name.
