Subject: [PATCH] [ADD] sale_zero_stock_approval: add zero stock approval
 control on sale orders

In standard behavior, sales users can confirm orders even when there is
not enough available stock, which may lead to unintended commitments,
stock issues, or reliance on manual validation processes.

This change introduces a *Zero Stock Approval* mechanism to enforce
better control over such scenarios.

A boolean field is added on the sale order to explicitly allow
confirmation when stock is insufficient. For regular sales users, this
field acts as a required approval flag: they cannot confirm the order
unless it is enabled.

To maintain flexibility and align with existing access rights, sales
managers are not restricted by this rule and can confirm orders
regardless of stock availability or field value.

The field is read-only for regular users to prevent unauthorized changes,
while administrators can manage it as needed.

The confirmation logic is extended to validate stock availability per
order line and block confirmation when the conditions are not met.

This ensures that zero-stock sales are intentional, traceable, and
aligned with business approval workflows.
