frontend: Add ApplicationInsights to the frontend

[sniok]

Basic setup for the analytics

1. Sets up AppInsights instance, runs before the app to capture as much as possible
2. Sets up custom trackEvent trackException functions
3. Integrates into our existing headlamp event to automatically track those
4. Integrates into out ErrorBoundaries to report those errors
5. Provides trackEvent trackException functions to plugins

(CI fails as expected)

How to test

1. Open the app, perform some actions
2. Validate /track network requests
3. Validate that events are showing up in the app insights

Pull request overview

Adds a basic Microsoft Application Insights (AppInsights) integration to the frontend, wiring telemetry into existing Headlamp events, error boundaries, and the plugin API surface.

Changes:

• Initialize AppInsights early via a new analyticsSetup.ts module loaded from index.html.
• Add trackEvent / trackException helpers and invoke them from Headlamp event middleware and ErrorBoundary.
• Expose analytics helpers through window.pluginLib for plugins; add required npm dependencies.
