fix(portal): force outer breadcrumb container on every /my/* page

Odoo stock routes (/my/orders, /my/invoices, etc.) call
portal.portal_searchbar with breadcrumbs_searchbar=True, which made
portal.portal_layout suppress its outer breadcrumb container — the
breadcrumb then rendered inside the searchbar nav, which lives inside
our shell's <main> and showed up in the right column. We can't edit
the stock route handlers, so override portal.portal_layout in
fp_portal_shell to ignore breadcrumbs_searchbar (still respect
no_breadcrumbs and my_details). CSS-hide the now-duplicate inline
breadcrumb inside .o_portal_navbar so we don't show two trails.
