fix(plating): trim default SO order-line columns to the plating set

Default-hide six order-line columns that aren't part of the plating
view (Product/product_template_id, Description Template, Specification,
Delivered Qty, Invoiced Qty, Taxes) by flipping them to optional="hide".
They stay available via the optional-columns toggle. Default-visible set
is now Customer-Facing, Part, Process/Recipe, Thickness, Serial, Job #,
Effective Deadline, Qty, Unit, Unit Price, Amount — for both quotations
and sales orders.
