fix(api): fix batch user-files delete recursive CTE query

The refactored CTE used = ANY(${validIds}::uuid[]) which Drizzle
serializes as a scalar text parameter with a ::uuid[] cast. Since
the user_files.id column is text (not uuid), PostgreSQL rejects
the text = uuid comparison. Replace with IN (...) via sql.join()
to pass each ID as a plain text parameter matching the column type.
