Enable code folding in the console response panel

[KShivendu]

What

Turns on Monaco's code folding in the response (right-hand) pane of the Console, so long JSON responses can be collapsed block by block the way they can in a code editor.

Folding was explicitly disabled (folding: false) in the result editor, so the only way to navigate a large response was scrolling which can become very annoying if your collection/cluster/telemetry data is huge.

-        folding: false,
+        folding: true,

Notes

• No new dependency and no other options needed: language="json" already gives Monaco a folding-range provider (the JSON worker is wired up in EditorCommon), so the default auto strategy produces bracket-accurate fold ranges.
• Every other folding default is left alone, so the response pane now behaves exactly like the request pane: controls appear on gutter mouseover, and folded ranges are highlighted.
• The request editor is untouched — it never disabled folding, so it already had this.

Test plan

• Ran a points/scroll query in the Console against a local Qdrant and confirmed the fold arrows appear in the response gutter on hover and collapse/expand nested objects and arrays.
• prettier --check and eslint pass on the changed file.
