-- get_dashboard_nav_flags(p_company_id): the two booleans the dashboard
-- layout needs to decide whether to render the Webshop and Körjournal nav
-- rows, in ONE round trip instead of four limit-1 selects on the critical
-- path of every hard load (woocommerce_connections, shopify_connections,
-- webshop_orders, mileage_trips).
--
-- SECURITY INVOKER: RLS on the four tables applies as usual, so a caller who
-- is not a member of p_company_id sees (false, false), never another
-- company's flags. STABLE: pure reads. EXECUTE only for authenticated.
