fix(portal): sidebar values + Purchase Order naming on /my/orders detail

1. Odoo's portal_order_page route calls _get_page_view_values which
   doesn't touch _prepare_portal_layout_values, so our sidebar
   context (fp_sidebar_items, fp_partner_display_name) was missing
   on every Odoo detail page (SO, invoice, delivery, quote). Override
   _get_page_view_values to setdefault our two keys into the values
   dict — non-clobbering, covers every detail route.

2. Rename "Sales Order(s)" / "Your Orders" to "Purchase Order(s)" on
   the customer portal so the wording matches the sidebar item and
   the customer's perspective (they purchase from us). Inherits in
   fp_sale_order_portal.xml replace the relevant text nodes in
   sale.portal_my_home_menu_sale / sale.portal_my_orders /
   sale.sale_order_portal_content.
