[IMP] product_cost_security: hide standard_price column in product tree views

Adds the 'product_cost_security.group_product_cost' group restriction
to the 'standard_price' field in both product.product and
product.template tree views.

This ensures that users without the explicit cost permission cannot
visualize the cost column when triggering the "Search More" popup from
sale orders or when accessing the default list views, strictly enforcing
the visibility criteria.
