refactor(routines): streamline suggest prompt — merge inventory context, add leaving_home SPF hint

- Remove _build_inventory_context; fold pao_months into DOSTĘPNE PRODUKTY entries
- Remove "Otwarte równolegle" duplicate section from prompt
- Rename OSTATNIE RUTYNY (7 dni) → OSTATNIE RUTYNY
- Add _build_day_context and SuggestRoutineRequest.leaving_home (optional bool)
- System prompt: replace unconditional PAO rule with conditional; add SPF factor
  selection logic based on KONTEKST DNIA leaving_home value
- Frontend: leaving_home checkbox (AM only) + i18n keys pl/en

   - najpierw zużywaj produkty już otwarte,
   - minimalizuj liczbę jednocześnie otwartych produktów funkcjonalnie podobnych,
   - nie rozpoczynaj nowego produktu, jeśli istnieje funkcjonalny odpowiednik otwarty i kompatybilny,
-  - preferuj produkty z krótszym terminem ważności po otwarciu (expiry_date / PAO),
+  - jeśli nearest_open_pao_deadline lub nearest_open_expiry jest dostępne, preferuj produkt z wcześniejszą datą w swojej kategorii,
   - rotuj tylko gdy daje to wartość terapeutyczną.
 - Nie łącz retinoidów i kwasów w tej samej rutynie ani tego samego dnia (dla planu wielodniowego).
 - W AM zawsze uwzględnij SPF, jeśli kompatybilny produkt SPF istnieje na liście.
+  Wybór filtra (na podstawie KONTEKST DNIA):
+  - "Wyjście z domu: tak" → najwyższy współczynnik dostępny w nazwie (SPF50+, SPF50, SPF30);
+  - "Wyjście z domu: nie" → SPF30 wystarczy; wyższy dopuszczalny jeśli brak SPF30;
+  - brak KONTEKST DNIA → wybierz najwyższy dostępny.
 - Dla minoksydylu (jeśli celem jest zarost i produkt jest dostępny): ustaw adekwatny region
   broda/wąsy i nie naruszaj ograniczeń bezpieczeństwa.
 - Preferuj 4-7 kroków na pojedynczą rutynę; unikaj zbędnych duplikatów aktywnych.
