feat: Çözümler bölümü + mobil menü; admin parser düzeltmeleri

- Çözümler: solutions tablosu, /cozumler liste + detay sayfası, anasayfa
  bölümü, tam admin CRUD (/admin/cozumler), header & footer linkleri,
  projelerde solution_slug ilişkisi, services-grid genelleştirildi
- Mobil menü (hamburger drawer) eklendi — header artık < lg'de gezilebilir
- Site ayarları parser: textarea CRLF (\r\n) normalizasyonu — neden biz,
  süreç adımları, değerler ve SSS blokları artık doğru parçalanıyor
- homepage_faq + garanti (title/description/items) saveSiteSettings'e
  bağlandı (daha önce hiç kaydedilmiyordu)
