fix(recipe-generation): BRAND.name-interpolation för creatorDisplayName + rubriker/filnamn

feat(recommendation-engine,api): S4 Smak/Hälsa/Lager-vyer för 'Vad ska vi äta?'

- Ersätter hårdkodat 'Cibello' i scale-batch, scale-smoke-test och export-verified.
- DB-backfill: 224 recept hade 'Cibello AI' i creator_display_name (värdena
  motsvarar nuvarande BRAND.name, ingen rad ändrades men kontrollen är gjord).
- Lägger till view-query-param (default|taste|health|pantry) med fördefinierade
  ScoringWeights och samtyckesgrind.
- Unit-tester för vyer; integrationstester för vy-param, validering och
  fallback utan personalization-samtycke.
- brand-guard grön; pnpm typecheck 19/19; pnpm test --force x2 grönt (34 tasks,
  275 tester).
