Add uncategorised patterns GraphQL endpoint

Backend for the cookie banner detection page: a new
uncategorisedPatterns connection on CookieBanner with
sortable (NAME, LAST_MATCHED_AT, UPDATED_AT, SOURCE)
and filterable (text ILIKE on name/description, source
enum) paginated results. COALESCE handles NULL-first
ordering for last_matched_at.
