Fix nav active state & populate services menu

Task #9: Two header fixes on artifacts/ehsan-poc.

1. Nav active state no longer stuck on "فرص التبرع". Active page now gets
   a moving green outline box (Home) matching the real ehsan.sa nav.
   "فرص التبرع" stays a solid green CTA but only shows an active green ring
   when on /opportunities. Applied consistent active styling across desktop
   and mobile nav (Home, Opportunities, Request).

2. "خدماتنا" dropdown now lists the eight official services from the
   reference image, each with a lucide icon: غراس (Sprout), الزكاة
   (HandCoins), هدية (Gift), الأضاحي (Beef), الحملات (Megaphone), التبرع
   الدوري (Repeat), التبرع بالرسائل (MessageSquare), تطهير الأسهم
   (TrendingUp). Each routes to /opportunities (POC has no per-service
   pages). Kept "طلب دعم" below a separator so desktop users retain access
   to /request. Mobile menu mirrors the services list.

Added serviceItems i18n group (AR + EN) in translations.ts.

Files: src/components/layout/Header.tsx, src/lib/i18n/translations.ts.
Verified: tsc --noEmit clean; e2e UI test passed (active state moves,
dropdown shows all 8 items + request, routing works); console clean after
HMR-restart of the web workflow. No emojis.
