feat: surface mid-stream gadget errors to the user

[atharrva01]

Description:
If the gadget connection drops mid-stream (pod deleted, network issue, etc.), the UI used to just freeze while still showing “Running.”

I added a dismissible inline alert on the Gadget Details page so users immediately know the stream has failed instead of guessing.

Changes:

• Listen for WebSocket close events to catch dropped connections
• Pass a setStreamError callback through the renderer
• Show a MUI alert on error (auto-clears on next Start)

Before/After:

• Before: table frozen, still “Running,” no error

• After: clear “stream error” alert shown

hi @illume @ashu8912 , I added inline error handling so gadget stream failures are surfaced to users instead of silently freezing the UI.

Pull request overview

Surfaces mid-stream gadget/port-forward failures to users by detecting dropped WebSocket connections and displaying a dismissible inline error alert on the Gadget Details page.

Changes:

• Listen for underlying WebSocket close events in the port-forward hook to detect transport-level disconnects.
• Thread a setStreamError callback through renderer/callback layers to propagate stream failures up to the UI.
• Render a MUI Alert on Gadget Details when a stream error occurs and clear it on subsequent starts.
