feat: dölj SEK-receptkostnad för icke-SEK-användare + i18n:remove-language

- Recept-kostnaden ligger i SEK (basvaluta, D-028). För en spansk användare
  (currency != SEK) nollas estimatedCostMinorPerPortion i API:t (list + detalj)
  -> kostnads-taggen försvinner helt i stället för att visa en svensk SEK-siffra.
  (Beslut: hellre ingen uppskattning än fel valuta, tills riktpriser via kvitton/M8.)
- i18n:remove-language – motsvarighet till add-language, tar bort ett språk rent.
  Verifierat: add el -> remove el -> byte-rent, vakt + typecheck gröna.
