Kimi K2.7 Code is not available in Pro subscription

### Describe the bug

- I have a Copilot Pro subscription;
- The GitHub policy says that Kimi Code 2.7 (model `kimi-k2.7-code`) is available for Pro subscription.
- In fact, it is listed in the `Blocked / Disabled` list. Here is the screenshot.

Copilot CLI version:

Copilot Pro [availability](https://github.blog/changelog/2026-07-01-kimi-k2-7-is-now-available-in-github-copilot/):

### Affected version

Copilot CLI 1.0.68

### Steps to reproduce the behavior

1. Start Copilot;
2. Type `/model` and press Enter;
3. A screen with `Available` models is displayed and the list of models -- no `kimi-k2.7-code` model is displayed.
4. Press `Tab` key to switch to `Blocked / Disabled` -- `kimi-k2.7-code` is listed there (see screenshot)

### Expected behavior

_No response_

### Additional context

Run in Poweshell following command:
```powershell
copilot -p "Say OK" --model "Kimi-K2.7-Code"
```

Response:
```
Error: Model "Kimi-K2.7-Code" from --model flag is not available.
```

Reproduce the issue in Copilot CLI 1.0.68 by opening /model and checking the Available and Blocked / Disabled lists, then run the documented PowerShell command with --model "Kimi-K2.7-Code". Done means the model is available to Copilot Pro users and the command no longer reports that the model is unavailable.
