DavidandMichael Sloan 5fd187769d Add Codestral edit predictions provider (#34371)
Release Notes:

- Added Codestral edit predictions provider which can be enabled by adding an API key in the Mistral section of agent settings.

![2025-07-13 11 35
33](https://github.com/user-attachments/assets/8bf599d7-33c7-4556-b878-6c645d69661f)


## Config

Get API key from https://console.mistral.ai/codestral and add it in the Mistral section of the agent settings. 

```
  "features": {
    "edit_prediction_provider": "codestral"
  },
  "edit_predictions": {
    "codestral": {
      "model": "codestral-latest",
      "max_tokens": 150
    }
  },
```
