Fold secondary nav links into a «بیشتر» dropdown

Move مراکز درمانی + تقویم هفتگی into a native <details> «بیشتر» dropdown, leaving the bar with just
the primary items: خانه · استخدام · شیفت‌ها · آماده به کار · بیشتر ▾ · 🔎. Desktop shows a floating
menu; in the mobile burger panel it expands inline. Closes on outside click.
