chore(knowledge): drop the dead pre-redesign knowledge base sort

`sortKnowledgeBases` was a second, complete ordering for knowledge bases
(name/createdAt/updatedAt/docCount) left over from the old sort dropdown,
with no consumers since the shared Resource sort menu replaced it — the
kind of duplicate that silently diverges from the page it shadows.

Its `SortOption`/`SortOrder` types and the `SORT_OPTIONS` list that fed
it were dead with it. `utils/sort.ts` now holds only a filter, so it is
renamed to `utils/filter.ts`.
