Typo in the model name, no "s".

The model page lists them as Pixtral Large and Pixtral 12B. The direct links confirm the API names:

```
pixtral-large-2411 → pixtral-large-latest
pixtral-12b-2409 → pixtral-12b-latest
```

Documentation URL: https://docs.mistral.ai/getting-started/models/models_overview/

```bash
$ MISTRAL_KEY=$(grep MISTRAL_API_KEY /home/tac/g/sites/ai-pipeline-demo/.env.local | cut -d= -f2)
for model in "pixtral-12b-2409" "pixtral-12b-latest" "pixstral-12b-latest"; do
  result=$(curl -s -X POST https://api.mistral.ai/v1/chat/completions \
    -H "Authorization: Bearer $MISTRAL_KEY" \
    -H "Content-Type: application/json" \
    -d "{\"model\":\"$model\",\"messages\":[{\"role\":\"user\",\"content\":\"hi\"}],\"max_tokens\":3}")
  echo "$model: $(echo $result | python3 -c 'import sys,json; d=json.load(sys.stdin); print(d.get("choices",[{}])[0].get("message",{}).get("content","") or d.get("error",{}).get("message","")[:60])' 2>/dev/null)"
done

pixtral-12b-2409: Hello!
pixtral-12b-latest: Hello!
pixstral-12b-latest:
```
```bash
curl -s -X POST https://api.mistral.ai/v1/chat/completions \
  -H "Authorization: Bearer $MISTRAL_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"pixstral-large-latest","messages":[{"role":"user","content":"hi"}],"max_tokens":5}'
```

That returns "Invalid model: pixstral-large-latest". The pixtral name works.
