Tool call results that carry a non-empty error string (e.g. an object with an
"error" field such as {"error": "403 Client Error: Forbidden for url: ..."})
were always rendered with a green success check, so failures were invisible
until the user expanded the result.
Detect such error payloads and render a red error icon instead, both on the
per-call "View Result" button (ToolCallDisplay) and on the grouped
"Explored ..." summary (ConsecutiveDetailsGroup).

* on scalar values such as `JSON.parse('5') -> 5`, because `JSON.parse(5)` is
|
|
* `JSON.parse('5')` again. Unwrapping in a `while` loop avoids that
