Subject: [PATCH] [ADD] zero_stock_approval: restriction on SO confirmation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a new boolean field `zero_stock_approval` to sale.order to
control whether a sales user is allowed to confirm orders with
insufficient available stock.

Sales users (non-managers) cannot confirm a sale order when
stock is insufficient unless the approval checkbox is checked.
Sales managers can always confirm regardless of the field value.

This enforces business rules for zero stock approvals and keeps
the confirmation logic consistent with access rights.

The override of `action_confirm` checks each order line’s
stock availability and prevents confirmation if conditions
are not met.
