Sale Order Line Input

This module adds a new screen called "Sales Orders Lines" under the Sales menu. Instead of opening one sales order at a time, users get a single editable list of all sale order lines and can search, filter, group and create lines right there.

• The list is editable at the top, so a new line can be typed in directly. If no order is chosen, the line is created on a new sales order for the selected customer.
• Lines are colour-coded: draft lines are highlighted, cancelled lines are greyed out, lines to invoice are marked, and invoiced lines are shown in green.
• Columns include order, customer, product, description, quantity, delivered and invoiced quantities, unit of measure, unit price, taxes, discount, amount and total. Some columns are optional and can be shown or hidden.
• A "Forced company" field lets users pick the company used for prices and taxes, and the amount columns automatically show the right value depending on whether the company's prices are entered tax included or tax excluded.
• Extra filters and grouping options are added to the existing sales order line search view: filter lines that are or are not linked to an invoice, and group by order state, invoice status or unit of measure.

The module works on sale.order.line and depends on sale_management. It does not change how sales orders themselves are created or confirmed.
