Office tranche was computed but invisible in both export surfaces (жильё+паркинг
< GDV with an unexplained gap). Add «Выручка — нежилое (1-й этаж)» row to the PDF
financial table + concept cascade; relabel PDF VAT row «НДС (нежилое: паркинг +
коммерция)». Add office_area_sqm/revenue_office_rub to hand-maintained
concept-api types; make teap_synth.office_area_sqm optional in site-finder types
(dev mock on main lacks it). Fix ptica finance fixture for required
revenue_office_rub.
