fix(sale_ux): increment view_order_form_inherit_sale_project_ux's priority

Otherwise, sometimes installing the module would fail with:

odoo.tools.convert.ParseError: while parsing /opt/odoo/auto/addons/sale_project_ux/views/sale_order_views.xml:5
Error while validating view near:
<form string="Sales Order" class="o_sale_order">
            <header>
                <field name="authorized_transaction_ids" invisible="1"/>
Field 'visible_project' used in attrs ({'invisible': [('visible_project', '=', False)]}) must be present in view but is missing.
