[vm-repair] repair-button command fails with FrameLocalsProxy error in CLI >= 2.77.0

### Describe the bug

The az vm repair repair-button command fails when using Azure CLI versions 2.77.0 and above. The same command works correctly in Azure Cloud Shell(which has 2.77.0) and with CLI versions up to 2.76.0. This issue impacts automated repair workflows and SRE agent scenarios, especially for VMs with fstab issues.

### Expected behavior

The command should execute successfully and perform the repair steps without errors.

### Environment Summary

PS C:\Users\dpaladhi> az --version azure-cli 2.79.0 core 2.79.0 telemetry 1.1.0 Extensions: azure-devops 0.26.0 vm-repair 2.1.2 Dependencies: msal 1.34.0b1 azure-mgmt-resource 23.3.0 Python location 'C:\Program Files\Microsoft SDKs\Azure\CLI2\python.exe' Config directory 'C:\Users\dpaladhi\.azure' Extensions directory 'C:\Users\dpaladhi\.azure\cliextensions' Python (Windows) 3.13.9 (tags/v3.13.9:8183fa5, Oct 14 2025, 14:09:13) [MSC v.1944 64 bit (AMD64)] Legal docs and information: aka.ms/AzureCliLegal Your CLI is up-to-date.

### Additional context

The error occurs at the beginning of the process, before the three-step ALAR workflow starts.
The issue seems related to parameter handling in vm-repair extension after CLI core changes.
Relevant code line:
[repair_utils.py#L737](https://github.com/Azure/azure-cli-extensions/blob/e7519a9c5fd328e845d4aa980e84d331a5655553/src/vm-repair/azext_vm_repair/repair_utils.py#L737)
Possible workaround discussed: Downgrade CLI to 2.76.0 temporarily.
Impact: Blocks automated repair flows and demo scenarios for Ignite.
