The legacy sort=documentCount path wrapped its result with paged(top, 0,
safeSize, top.size()), so totalElements/pageSize looked like a paged slice of
a larger set when in fact the top-N query returns the complete result. Add a
dedicated PersonSearchResult.topN factory that reports reality — totalElements
= returned count, pageSize = that count, totalPages = 1 (0 when empty) — and
pin both the populated and empty semantics with controller tests.
