feat(person): paginate GET /api/persons and add confirm/delete endpoints

GET /api/persons now returns PersonSearchResult with server-side filter params
(type, familyOnly, hasDocuments, provisional) and page/size bounds (@Min/@Max
-> 400). review=true drops the clean reader default. The legacy
sort=documentCount top-N path is folded into the paged contract. Add
PATCH /{id}/confirm and DELETE /{id}, both WRITE_ALL-guarded. Remove the now
unreachable PersonService.findAll(String).

BREAKING-CHANGE: GET /api/persons response shape changes from a bare list to
PersonSearchResult { items, totalElements, pageNumber, pageSize, totalPages }.
