Get Brands With Portals Company Wide

Company-scoped brand+portal catalog for the per-brand portal settings page.

Unlike /brands-platforms, this endpoint does NOT require a PV: it lists every brand belonging to the authenticated company together with the full global portal catalog. Status per (brand, portal) comes from a separate call to GET /integrazu/portal-config/status; this endpoint only returns the catalog.

Used by /settings/portals so a company can submit portal credentials at the brand level (pv_id = NULL in Z_BrandPortalConfigurations) without first needing a vehicle.

Returns: [ { "brand_id": 1, "brand_name": "Stand ABC", "portals": [ {"id": 1, "slug": "standvirtual", "designation": "StandVirtual", "logo": "...", "enabled": False}, ... ] } ]
