Write a manual chapter for business units and business unit types

Table of Contents

This page is a capture in the inbox bucket of the product backlog — a pre-sprint idea, not yet pulled into a sprint as a story.

What

Write a user-manual chapter documenting business_unit and business_unit_type as reference-data entities in their own right, covering the org-structure concept, the Business Units and Business Unit Types list windows, and their detail dialogs. Both entities have full Qt implementations under ores.qt.refdata (BusinessUnitMdiWindow, BusinessUnitDetailDialog, BusinessUnitTypeMdiWindow, BusinessUnitTypeDetailDialog) but neither appears anywhere in the manual.

Why

Discovered while auditing the party/counterparty/party_status commissioning story for manual coverage of auxiliary lookup entities: business unit is a distinct org-structure concept (not a party/counterparty combo source like party_status/party_id_scheme are), and warrants its own chapter rather than a slot inside the Parties chapter.
