feat: hizmet ve proje detay sayfaları + galeri sistemi

Yeni Appwrite kolonları:
- services: content (markdown), features[], faq[] (JSON-encoded), hero_image
- projects: gallery[], content (markdown), client_name, industry, duration, service_slug

Public sayfalar:
- /hizmetler/[slug]: hero + features checklist + markdown content + FAQ accordion
  + ilgili projeler (service_slug eşleşmesi)
- /projeler/[slug]: hero + meta tablosu (müşteri/sektör/süre/yıl) + kapak görseli
  + markdown vaka çalışması + lightbox galeri + diğer projeler

Yeni componentler:
- components/gallery.tsx: lightbox galeri (keyboard nav, prev/next, ESC kapat)
- components/faq-list.tsx: accordion FAQ (tek seferde tek açık)

Admin formları:
- Hizmet formu: hero_image, content (markdown), features (virgülle), FAQ
  (her blok '---' ile ayrılır, ilk satır soru, kalanı cevap)
- Proje formu: gallery (her satıra bir URL), content (markdown), client_name,
  industry, duration, service_slug (dropdown — hizmetlerden seçim)

Linkler:
- ServicesGrid kartları → /hizmetler/[slug]
- ProjectsGrid kartları → /projeler/[slug] (live_url butonu ayrı, target=_blank)

29 route üretiliyor.
