Add PersonSearchResult (mirrors DocumentSearchResult shape) and PersonFilter
records, plus paired findByFilter/countByFilter native queries sharing one
WHERE clause so the rendered page and totalElements can never drift. Filters
(type, familyOnly, hasDocuments, provisional, readerDefault, q) each disable
via a null/false param. Tested against real Postgres via Testcontainers.
