feat(deploy): Gemini som committat prod-läge + hermetiska eval-fixtures

- config.ts: tillåt AAMOS_MODE=http|gemini i prod; mock förbjudet
- first-deploy.sh: Grind 1 accepterar gemini (kräv GEMINI_API_KEY);
  Grind 5 kör eval:scan mot gemini; Grind 8 behandlar gemini som riktig AI
- gemini.ts: stöd för data-URLer (inline base64-bilder) i fetchOneImage
- eval-fixtures: 4 lokala bilder (fridge-1, fridge-2, label-1, receipt-1)
- scan-eval.ts: läser lokala fixtures, inga externa hämtningar
- capture-eval.ts: använder lokal fixture som data-URL
