[FIX] stock_orderpoint_manual_update: keep qty_forecast in DOM to avoid XPath conflict with Studio

[fw-bot-adhoc]

Problem

When Studio is used on the stock.warehouse.orderpoint list view, it raises:

ValueError: El elemento "<xpath expr="//field[@name='qty_forecast']">" no se puede localizar en la vista principal

This happens because stock_orderpoint_manual_update used position="replace" to remove qty_forecast from the DOM entirely and substitute it with qty_forecast_stored. A sibling inherited view (stock.warehouse.orderpoint.tree.inherit) anchors its XPath on //field[@name='qty_forecast']. When Studio's apply_inheritance_specs override processes the view combination and applies the sibling view after the replace, the anchor no longer exists — raising the error.

Fix

Replace position="replace" with position="attributes" (making the field invisible instead of removing it from the DOM), then add qty_forecast_stored via a separate position="after". This keeps qty_forecast as a valid XPath anchor while hiding it from the UI.

<!-- before -->
<field name="qty_forecast" position="replace">
    <field name="qty_forecast_stored"/>
</field>

<!-- after -->
<field name="qty_forecast" position="attributes">
    <attribute name="column_invisible">1</attribute>
</field>
<field name="qty_forecast" position="after">
    <field name="qty_forecast_stored"/>
</field>
