feat: filtr jednostek multisplit, ostatnio oglądane, sklep pompy ciepła, czyszczenie komentarzy, checkbox zgody

- Filtr 'Ilość jednostek wewn.' w sklepie (1–9 jednostek, checkboxy, liczniki)
- Komponent RecentlyViewedProducts + Zustand store (recently-viewed-store.ts)
- Pompy ciepła dodane do sklepu i nawigacji (Header + MobileMenu)
- Logotypy marek zaktualizowane (Daikin, Panasonic + odświeżone istniejące)
- Checkbox zgody RODO w /zamowienie powiększony (w-5 h-5)
- Usunięcie ~65 zbędnych komentarzy WHAT z 12 plików (build: 0 errors)
