Changelog

Daangn realty operations now accept wider upstream enum sets for article status, building type, and management cost fields; the complex detail query migrates from ComplexIdQuery to ComplexDetailPageQuery; region search tolerates partial parent region shells; and building_type_label now resolves correctly.

This change tracks upstream schema drift in Daangn's realty GraphQL surface. All modifications are additive except the source rename on complex listing articles.
