fix: stop storing raw title template on subcontracting orders

subcontracting order and subcontracting inward order carry a hidden
title field defaulting to "{supplier_name}" / "{customer_name}", while
their title_field points at supplier_name / customer_name. document.
set_title_field() substitutes the template only when title_field is
"title", so every record stores the placeholder verbatim.

drop the dead default and hidden flags, move title into the other info
tab to match purchase order, and add a patch to repair existing rows.

(cherry picked from commit 5008e6126f)
