Description

This PR attempts to address Issue #9128 by adding the devstral-small-latest model to the Mistral provider configuration. The model has been added with appropriate specifications based on the pattern of other models in the configuration:

• Model ID: devstral-small-latest
• Max Tokens: 65,000 (smaller than medium variant)
• Context Window: 65,000
• Supports Images: true (like other devstral models)
• Input Price: $0.2 (more economical than medium at $0.4)
• Output Price: $1.0 (more economical than medium at $2.0)

This provides users with a more economical option for the devstral family of models, as requested in the issue.

Test Procedure

1. All existing tests continue to pass (npm test in packages/types)
2. Type checking passes (npm run check-types)
3. Linting passes (npm run lint)
4. The model should appear in the Mistral provider selection after integration
