For sale orders, if the invoice status is set to "Fully Invoiced", the mount to invoice is forced to zero.

The VoIP interface was updated to use newer platform capabilities and avoid unnecessary data conversion when displaying repeated items. This is a small internal improvement that can help keep the calling interface cleaner and more efficient without changing user workflows.

As of Owl 2.2, it is now possible to use iterable directly in t-foreach without having to convert it to array first.

This commit takes advantage of this new feature to remove the unnecessary array conversions from the VoIP code.
