feat(i18n): översätt kvarvarande vyer + härda vakten (audit-backlog)

- API: översatt title/displayName/toName läggs nu bredvid Sv-fälten i favoriter,
  receptvarianter, /scaled, skapar-profiler, topplistor, memory-impact,
  substitutions — samt de denormaliserade titlarna (min dag, historik, matlådor,
  matlåde-förslag, veckoplan) via nullable recipeId med svensk fallback.
  10 endpoints, batchade resolvers (ett anrop per endpoint).
- Mobil: konsumerar de nya fälten med ?? Sv-fallback (swap-meal, sparade recept,
  varianter, min dag, logg, matlådor, veckoplan, inköpslista). Hårdkodade
  strängar -> t() (kitchen, scan-review, register, recept protein/Skapat av);
  decimalkomma -> Intl.NumberFormat. Allergen-etiketter -> t() (+5 nya nycklar).
  11 nya nycklar i alla 12 språk.
- i18n-vakt härdad: fångar nu hårdkodad svenska i prop={`...`}-mallliteraler
  (blind fläck förr). Verifierat att den fäller men inte ger falska positiv.
- whySv var redan lokaliserad (buildWhy med språktagg) - orörd.
- typecheck grönt (alla paket), vakt grön (603 nycklar).
