[FEATURE] View Helm Releases in AKS Desktop

## Feature Summary

Add a dedicated view within AKS Desktop to list, inspect, and monitor Helm releases running on selected Azure Kubernetes Service clusters.

## Motivation

Managing Helm deployments currently forces users out of the AKS Desktop GUI and into the terminal to run repetitive helm list, helm status, or helm history commands. Switching context to verify whether a chart deployed successfully, check current revision numbers, or inspect release values breaks the visual management workflow that AKS Desktop provides.

## Detailed Description

Release List View: Display active, failed, and pending Helm releases across target namespaces, showing release name, namespace, chart version, app version, status (e.g., deployed, failed), and last updated timestamp.

Detail Inspector: Allow users to click a release to view its deployed values (values.yaml), manifest output, revision history, and associated Kubernetes resources (Pods, Services, Ingresses).

Search & Filter: Filter releases by namespace, status, or keyword search.

## Use Cases

I want to see all deployed Helm releases in a cluster panel so that I can quickly verify if automated CI/CD deployments succeeded without opening a CLI.

When troubleshooting an application failure, I need to inspect the active Helm release values and revision history to determine if a recent chart upgrade introduced a configuration issue.

Start by reviewing the existing AKS Desktop cluster panel and workload-management entry points, then compare the requested release data with helm list, helm status, and helm history. Done means a dedicated view can list, search, and filter releases, inspect values, manifests, revisions, and associated resources across selected namespaces.
