Subject: [PATCH] fix(accounting): tax report cost side queried a non-existent
 column
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The tax-report cost query selected inbound_documents.description, but that
column only exists on the 'expenses' table — inbound_documents has none. On
Postgres this threw 'column inbound_documents.description does not exist',
so the whole cost side failed with 'Costs could not be loaded'.

Use inbound_documents.invoice_number (an existing column, same descriptor
ledgerService surfaces) as the cost-row label instead. Expense rows still
use their real expenses.description column.
