Resolve wikilinks to /s/<spaceSlug>/p/<slugId> via buildPageUrl instead of
the inexistent /page/<uuid> route. Persist slugId and spaceSlug as node
attributes so the URL can be rebuilt from the document alone, without an
extra lookup round-trip.
The client extension now .extend()s the shared WikilinkNode from
@docmost/editor-ext to keep the schema identical between client and the
Hocuspocus server.
