refactor(person): unify fill-blank under preferHuman and clarify rowId trap

Browse Source 
Unify birthYear/deathYear fill-blank logic under an Integer preferHuman overload so
every canonical field uses one self-documenting precedence idiom, and add a guard
test pinning year fill-blank vs human-edit preservation. Add a comment in
PersonTreeImporter.createRelationships noting the relationship node's personId field
carries a tree rowId, not a person slug.
