i18n(säsong+kock): lokalisera säsongsnamn (12 språk), snyggare tidshint, rensa dubbletter

- Säsong/högtidschippen på "Vad ska vi äta?" visade marknadens namn på svenska
  även för icke-svenska språk (SE-marknadens event saknar nameLocalized). Nu
  renderas de via i18n-nyckeln season.<slug> (t med defaultValue -> serverns namn
  som fallback för egennamn m.m.). SE-marknadens 14 event översatta i alla 12
  språk; egennamn (Navidad, Midsommar, Lucia...) behålls, beskrivande översätts
  (Kräftskiva, Skolstart, Grillsäsong...).
- Kok-läget: den boxade ⏱-rutan (såg ut som en knapp/timer och kunde misstas för
  en riktig timer) ersatt med en diskret rad "⏱ Ungefär {time}". Döda nycklar
  cooking.timer/timerDone/timerRunning borttagna; cooking.timerHint -> approxTime.
- Städat 2 dubblettnycklar i alla 12 locale-filer (mealbox.eatBy, common.remove)
  som låg kvar sedan tidigare leveranser (i18next tog sista värdet ändå).
- Vakt + typecheck gröna. 591 nycklar.
