AI-admin: katalog lar deg velge nøkkel — direkte API eller OpenRouter

- Ny mapping fra OpenRouter-provider til LiteLLM direkte-prefiks
  (google→gemini/, anthropic→anthropic/, openai→openai/, x-ai→xai/)
- «Legg til»-knappen i katalogen viser nå to dropdowns: alias + nøkkel
- Velger du Google-nøkkel → gemini/modellnavn, OpenRouter → openrouter/google/modellnavn
- Inline picker respekterer også valgt nøkkel i provider-skjemaet
